WNCG Seminar: 6G@Tek - Defining Future Test, Measurement and Sustainment Paradigms
WNCG Seminar: 6G@Tek - Defining Future Test, Measurement and Sustainment Paradigms

September 14, 2022 12:00 pm - 1:00 pm

Sixth-generation (6G) cellular communication systems demand new and innovative means to ensure communications are dynamic, effective, and efficient. Namely, broadband communication needs to be seamless as users migrate across multiple venues—vehicle, home, office, or wilderness, demanding high bandwidth offering for various communication scenarios.

Tektronix feels the separation between manufacturing and deployment will fade over time, compressing traditional test and measurement (T&M) processes. In the foreseeable future, time to market will demand T&M products help system modules comprehend their roles, ensuring alignments via Machine Learning or Artificial Intelligence: namely, they will work in conjunction with dedicated T&M controllers to ensure desired performance goals and system assurances.

Tek Collaboration with The University of Texas at Austin through the 6G@UT Research Center looks to promote research vectors that lead to innovative methods, algorithms, and network technologies that marry pervasive sensing, computing, communications, and optics to ensure 6G performance T&M needs are met.

Bio:

Mr. Keith R. Tinsley of Tektronix, a Fortive Company, has been in the industry for 25+ years. He received his BSEE from Old Dominion University and his MSEE from Arizona State University, always focused on wireless communications, decision theory and digital signal processing. In addition to publications and patents, his contributions also span satellite and mobile communication system, beginning with Iridium, stretching through Teledesic—both pioneering satellite systems—to traditional radio architecture networks and components, e.g. Oregon & Washington State Public Safety Radio Networks to mobile & RF handset designs. Currently, Keith is an RF Solutions Architect driving 6G@Tek by fostering innovative technologies at key universities to meet the anticipated need of wireless, wired, automotive and optical systems in serving as the pillars of 6G; thereby, Tektronix provides test, measurement, and sustainment offerings to help Fortive customers retire their risks and multiply our impact.

WNCG Seminar: Connections between Unsourced Multiple Access and Sparse Recovery
WNCG Seminar: Connections between Unsourced Multiple Access and Sparse Recovery

September 29, 2022 2:00 pm - 3:00 pm
EER 3.646

Krishna Narayanan
Professor
Texas A&M University

Multiple access communication has been studied extensively in information theory and wireless communications for several decades. Simultaneously, sparse recovery problems including compressed sensing, group testing, neighbor discovery in wireless networks, and datastream computing have also been studied in depth within their respective research communities. Although connections between multiple access and sparse recovery were pointed out as early as the 1980s, these fields have emerged mostly independently.

A particular version of multiple access communication, called unsourced multiple access has become very popular recently due to its relevance for the Internet of Things and Grant-free multiple access in 5G cellular standards. In this talk, we will show that there are strong connections between designing encoding and signal processing schemes for unsourced multiple access, and designing sensing matrices and recovery algorithms for sparse recovery problems in large dimensions. We will show how these connections can be gainfully exploited for designing algorithms with manageable complexity for both unsourced multiple access and sparse recovery. Our proposed techniques have applications in massive multiple access, neighbor discovery, lossy compressed sensing, heavy hitters problems, and group testing.

This is joint work with Prof. Jean-Francois Chamberland and several former and current graduate students at Texas A&M University.
