July 20, 2023DEEP LEARNING FOR MASSIVE MIMO HYBRID BEAMFORMING – HYBRID EVENTDr. Mishra
The millimeter-wave (mm-Wave) massive multiple-input multiple-output (MIMO) communications employ hybrid analog-digital beamforming architectures to reduce the cost-power-size-hardware overheads arising from the use of extremely large arrays at this band. Lately, there is also a gradual push to move from the millimeter-wave (mmWave) to Terahertz (THz) frequencies for short-range communications and radar applications to exploit very wide THz bandwidths. At THz, ultramassive MIMO array is an enabling technology to exploit ultrawide bandwidth while employing thousands of antennas. The design of the hybrid beamforming techniques requires the solution to difficult nonconvex optimization problems that involve a common performance metric as a cost function and several constraints related to the employed communication regime and the adopted architecture of the hybrid system(s). There is no standard methodology for solving such problems and usually, the derivation of an efficient solution is a very challenging task. Since optimization-based approaches suffer from high computational complexity and their performance strongly relies on the perfect channel condition, we introduce deep learning (DL) techniques that provide robust performance while designing a hybrid beamformer. In this talk, the audience will learn about applying DL to various aspects of hybrid beamforming including channel estimation, antenna selection, wideband beamforming, and spatial modulation. In addition, we will examine these concepts in the context of joint radar-communications and intelligent-surfaces-aided architectures.

July 28, 2023Wireless – public policy, health and safety
Abstract: This talk will provide insights into how wireless spectrum gets allocated, cell towers are
regulated and the public safety aspects of wireless devices. Although government regulators have clear
rules and regulations to monitor, it is typically known only to the product houses or to the contractors
who build towers, not the general public.
This talk will take the audience through both the technical and social aspects of these regulations.
Origins of safety in wireless was brought about over a period of several decades based on extensive
work. In the USA, the FCC largely monitors and regulates. Due to lack of transparency, often building cell
towers run into considerable opposition from the public – pros and cons of such public debates will be
discussed.

FUTURE OF ANTENNA DESIGN PROCEDURES AND CHARACTERISTIC MODE ANALYSIS

Microstrip antennas are in massive demand for several emerging applications such as biomedical devices, ultrawideband communication devices, radar applications, etc. Microstrip antennas are inherently narrowband and low gain antennas. Since their inception, various methods have been introduced to improve them. Most of the methods depend on the software that needs unlimited optimization runs, which increases the antenna design’s computation cost. Theory of Characteristic Modes (TCM) is the powerful analysis technique that made antenna structure easy to understand and comprehend. As it gives physical insight into the antenna’s structure, the analysis and design of the antenna may not need many optimization cycles. It was first introduced in the 1970s, but it was not till 2007 that this method hit the modern world again for planar antenna design. The reason behind the unmatched success of this method was the details it gives about the surface current behavior of the antenna in a user-friendly manner. Since then, CMA (Characteristic Mode Analysis) has been successfully applied to analyze planar structures and helps design and improve specific characteristics of antennas. Most of my research focused on designing and optimizing the UWB antennas using CMA. CMA can fully illustrate antenna structure with a finite number of resonant modes. Hence, it has the potential of simplifying complicated and tedious antenna design procedures.
This talk will focus on the following: (a) Can characteristic modes analysis define the future of antenna design procedures by helping to reduce the complexity of antenna design procedure? (b) the possibilities of producing the compact and efficient antenna design using characteristic modes. (c) how surface currents can be controlled to produce optimized antenna designs.

VTS Lecture with Dr. Mahrukh Khan, Ph.D. of The College of New Jersey (TCNJ)

Date: 16 Mar 2022
Time: 06:30 AM to 08:00 PM
Machine Learning at the Wireless Edge

Wireless networks can be used as platforms for machine learning, taking advantage of the fact that data is often collected at the edges of networks, and also mitigating the latency and privacy concerns that backhauling data to the cloud can entail.  Focusing primarily on federated learning, this talk will discuss several issues arising in this context including the effects of wireless transmission on learning performance, the allocation of wireless resources to learning, and privacy leakage.
