Abstract: This talk will provide an overview of ways in which machine learning and data-driven signal processing are impacting wireless sensing systems, spectrum anomaly-detection and analytic systems, and leading to powerful spectrum awareness capabilities which help to provide security, monitoring, and adaptation tools never previously possible at scale in wireless systems. We’ll talk about some of the work we’ve done at both DeepSig and VT to enable this, highlighting several works which illustrate how AI/ML based edge processing provide valuable security tools which fill significant gaps in the wireless threat surface which were previously prohibitive or highly manual and labor intensive to address. We’ll show some examples of how these approaches can be rapidly adopted from applied research into fieldable commercial systems, and considering their potential impact in securing and optimizing future wireless systems. Finally, we’ll also consider the impact of data driven baseband processing for wireless transmission and reception – The concept of an AI-Native Air Interface – often in a form resembling a channel autoencoder, presents a powerful tool for optimizing physical layer waveforms for hardening against a wide range of wireless threats and failure modes. We’ll highlight some of our work as well as others in this area, and consider where this can help optimize wireless security and resilience in communications systems in the future. Finally, we’ll consider future areas for research, industry adoption of techniques, and potentially transformative wireless security trends going forward.

Title: Rethinking Modern Communication from Semantic Coding to Semantic Communication

Time and Date: Thursday, Dec. 1, 2022 at 9:00AM US Eastern Standard Time

Presenter:  Professor Honggang Zhang, Zhejiang University, China

Venue: (Password: 4Zn7xZ)

Abstract: Modern communications are usually designed to pursue a higher bit-level precision and fewer bits while transmitting a message. We give a rethinking on these two fundamental features and introduce the concept and advantage of semantics that take advantage of a new kind of semantics-aware communication framework, incorporating both the semantic encoding and the semantic communication issues. After analyzing the underlying defects of existing semantics-aware techniques, we establish a confidence-based distillation mechanism for the semantic coding problem and put forward a reinforcement learning (RL)-powered semantic communication solution, which endow a communications system the ability to convey the semantics instead of pursuing the bit level accuracy. On top of these technical contributions, this talk provides a new insight to understand how the semantics are processed and represented in a semantics-aware coding and communication system, and verifies the significant benefits of doing so. Targeting at the next-generation (6G) semantics-aware communication, a number of critical concerns and open challenges such as the information overhead, semantic security and implementation cost are also discussed and envisioned.

Title: Holographic Radio: A New Paradigm for Ultra-Massive MIMO

Time and Date: July 22, 2022, at 9:00AM ET

Presenter:  Professor  Lingyang Song, Peking University, China

Venue: (Password: 4Zn7xZ)

Abstract: To enable a ubiquitous intelligent information network, the forthcoming sixth generation (6G) wireless communications are expected to provide revolutionary mobile connectivity and high-throughput data services through ultra-massive multiple input multiple output (MIMO). Widely-utilized phased arrays relying on costly components make the implementation of ultra-massive MIMO in practice become prohibitive from both cost and power consumption perspectives. The recent developed reconfigurable holographic surfaces (RHSs) composing of densely packing sub-wavelength metamaterial elements can achieve holographic beamforming without costly hardware components. By leveraging the holographic principle, the RHS serves as an ultra-thin and lightweight surface antenna integrated with the transceiver, thereby providing a promising alternative to phased arrays. In this talk, we will first provide a basic introduction of RHSs. We then introduce the unique features of RHSs which enables ultra-massive MIMO for both communication and sensing, in a comprehensive way. Related design, analysis, optimization, and signal processing techniques will be presented along with typical RHS-based applications for wireless communications. The implementation issues along with our developed prototypes and experiments will also be discussed.

Title: AI and Privacy in Collaborative Spectrum Sharing: Perspectives from the Spectrum Collaboration Challenge and Beyond

Date and Time: April 27, 2022 at 10AM ET

Registration Process: Please register at

Abstract: Dynamic spectrum access has the potential to greatly improve the utilization of the radio spectrum over existing static allocation techniques. Systems like Citizens Broadband Radio Service (CBRS) are first steps in realizing this vision. However, CBRS is still very limited in its need for centralized coordination (via spectrum access systems) and the potentially long delays (up to 24 hours) in issuing new spectrum grants. In the DARPA Spectrum Collaboration Challenge (SC2), teams performed distributed and collaborative spectrum sharing with spectrum usage patterns changing on time-scales of seconds. This was facilitated by the exchange of information via a collaboration channel, including teams’ usage of spectrum across time and space, as well as information on teams’ performance in delivering traffic. Although this data greatly helps in developing strategies for spectrum use, it also presents risks from both the disclosure of private information and from the potential for manipulating systems’ actions through misreporting. In this talk, I will discuss our experiences in collaborative spectrum sharing during the SC2, our work on applying ML to these problems, and our work on providing privacy in distributed spectrum sensing. I will conclude with a discussion of open problems in these areas.

Title: Algorithmic Sensing in the Age of Artificial Intelligence

Time and Date: Apr. 8, 2022, at 9:00 am ET

Presenter:  Professor  Jun Luo, Nanyang Technological University, Singapore

Venue: (Password: 4Zn7xZ)

Abstract: Promoted by the increasing compactness of embedded sensors and tremendous progress in artificial intelligence, algorithmic sensing is gaining momentum as it has the potential to push the limit of physical sensors. However, realizing the promises of algorithmic sensing can be highly non-trivial, as specific machine/deep learning techniques have to be fine-tuned to suit diversified sensing modalities, as opposed to direct feature extraction and classification largely ignoring the distinctive physics of respective sensors. In this talk, we take Radio Frequency (RF) sensing as a representative example. We first explain the basic idea of RF-based algorithmic sensing, then we present a unified framework to prepare RF sensing data for deep analytics. Building upon this framework, we further explain the peculiarity of RF sensing data (against, e.g., conventional image data) and present our approaches in designing deep interpreted RF sensing, leveraging our latest developments on a (software-defined sensing) platform, along with corresponding applications and products as instances.

Title: Machine Learning Classification of RF Signals over Congested and Contested Spectrum: Algorithms and Experimentation

Date and Time: February 23, 2022 at 11AM ET

Registration Process: Please register at

Abstract: Machine learning (ML) has recently been applied for the classification of radio frequency (RF) signals. One use case of interest relates to the discernment between different wireless protocols that operate over a shared and potentially contested spectrum. Although highly accurate classifiers have been developed for various wireless scenarios, research points to the vulnerability of such classifiers to adversarial machine learning (AML) attacks. In one such attack, a surrogate deep neural network (DNN) model is trained by the attacker to produce intelligently crafted low power “perturbations” that degrade the classification accuracy of the legitimate classifier. In this talk, I will first present several novel DNN protocol classifiers that our team designed for a shared spectrum environment. These classifiers performed quite well in both simulations and OTA experimentation, considering benign (non-adversarial) noise. I will then present several AML techniques that an attacker may use to generate low power perturbations. When combined with a legitimate signal, these perturbations are shown to uniformly degrade the classification accuracy, even in the very high SNR regime. Different attack models are studied, depending on how much information the attacker has about the defender’s classifier. These models range from a “white-box’” attack (attacker has full knowledge of the defender’s DNN, including its hyperparameters, its training dataset, and even the seeds used to train the network), to a “black-box” attack. Time permitting, I will discuss possible defense mechanisms as well as other research efforts related to detection of adversarial transmissions.

Title: Printable Smart Surfaces for IoT Communication and Sensing

Time and Date: November 17, 2021, at 9:00 am ET

Presenter:  Professor  Xinyu Zhang, University of California San Diego, USA

Venue: (Password: 4Zn7xZ)

Abstract: Embedding sensing and communication capabilities seamlessly into ambient environment is a long-term aspiration of the Internet of Things (IoT). Smart surfaces, with conformable shape, thin form factors, and ease of fabrication, can potentially materialize the vision of intelligent and connected things. In this talk, I will present the design of passive, batteryless, chipless smart surfaces that facilitate IoT communication and sensing.  These surfaces can be fabricated through ordinary inkjet printing, PCB printing, or 3D printing.  They can help sensing the interaction between human users and everyday objects, thus enabling challenging use cases such as experience sampling and mobile VR interaction.  In addition, they can communicate with ordinary radio/radar devices, and boost the quality of existing wireless links. Realizing such capabilities involves non-trivial challenges, especially since the surfaces are fully passive and do not possess the computing/communication components in typical IoT devices.  This talk will introduce a set of solutions that span the areas of electromagnetics, wireless communications, and application-specific signal processing.
