IEEE SPS Virtual Lecture- Enabling the Next Generation of Advanced Software-Defined RF Systems
IEEE SPS Virtual Lecture- Enabling the Next Generation of Advanced Software-Defined RF Systems
Abstract. After providing a brief introductory survey of recent and current efforts at the Center for Wireless Information Systems and Computational Architectures (WISCA), and observations on the future of RF systems, we introduce our efforts on the next generation of coarse-scale heterogenous processor development. On our project – entitled Domain-Focused Advanced Software-Reconfigurable Heterogeneous (DASH)-System-on-Chip (SoC) that operates under the DARPA Domain-Specific System-on-Chip (DSSoC) program – we are constructing both a development framework and an example SoC. Our SoC and framework will provide efficiency that approaches that of full-custom integrated circuits while enabling ease of programming that is similar to that of traditional scalar processors. To achieve this goal, we pursue significant progress in application ontological analysis, program and debugging software tools, intelligent on-chip resource management, flexible high-performance on-chip networking, and advanced task-specific accelerators. Additionally, to assure usefulness to DoD RF applications, we work with multiple traditional defense contractors on transitioning the DASH-SoC to example systems. We lead a broad team from academia, commercial industry, and traditional defense contractors. Biography. Prof. Daniel W. Bliss (bliss.asu.edu) is a Professor in the School of Electrical, Computer, and Energy Engineering at Arizona State University and a Fellow of the IEEE. He is also the Director of ASU’s Center for Wireless Information Systems and Computational Architectures (wisca.asu.edu). Dan received his Ph.D. and M.S. in Physics from the University of California at San Diego (1997 and 1995), and his B.S. in Electrical Engineering from ASU (1989). His current research focuses on advanced systems in the areas of communications, radar, precision positioning, advanced computational systems, and medical monitoring. Dan has been the principal investigator on numerous projects including sponsored programs with DARPA, ONR, Google, Airbus, and many others. He is responsible for foundational work in electronic protection, adaptive multiple-input multiple-output (MIMO) communications, MIMO radar, distributed-coherent systems, and RF convergence.

Celebrating Georgia Women in STEM
Celebrating Georgia Women in STEM
Atlanta WIE is co-hosting this event next Wednesday with several notable Georgia women in STEM, including Cassandra Wheeler, Regional Director for Georgia Power, and our own Theresa Brunasso, IEEE Region 3 Director-elect and engineering entrepreneur. In addition to hearing about their journeys, there will be breakout rooms for Q&A and a speed networking session to meet other local women in STEM. (The speed networking is fun, give it a shot!) See the attached flyer for information, and register (https://hopin.com/events/celebrating-georgia-women-in-stem). Co-sponsored by: Science for Georgia, Association for Women in Science-Georgia Chapter, Women in Biology-Atlanta Chapter Atlanta , Georgia, United States, Virtual: https://events.vtools.ieee.org/m/277941
IEEE COMSOC CHAPTER TECHNICAL TALK – The ABCs of Orthogonal Frequency Division Multiplexing (OFDM) Part II
IEEE COMSOC CHAPTER TECHNICAL TALK – The ABCs of Orthogonal Frequency Division Multiplexing (OFDM) Part II
This is Part II of a Two Part Talk on OFDM. The abstract below is for both Part I and II: The main benefit of OFDM is its ability to cope with severe multipath channel conditions without the need for complex equalization filters. How does it accomplish this? The short answer: by "dividing and conquering." It partitions a high-data-rate signal into smaller low-data-rate signals so that the data can be sent over many low-rate sub-channels. The Time/Frequency relationships are presented with a figure that facilitates a straightforward understanding of the OFDM partitioning process. We emphasize the important role of the cyclic prefix (CP). We show how it allows us to change linear convolution into circular convolution, thereby purging any transients, which helps to maintain waveform orthogonality at the receiver. OFDM waveform synthesis is covered in detail. Also, the spectral properties of Real and Imaginary signals are reviewed. We further consider the peak-to-average power ratio (PAPR) in OFDM, and how the desire for small PAPR has given rise to a special variant of OFDM called single-carrier OFDM (SC-OFDM). Finally, we illustrate applications of this elegant technology in standards such as 802.11 and LTE.
