Computer Engineering Seminar

Speaker: Dr. David Garrett, Broadcom

Talk Title: Transmit Beamforming in WiFi (IEEE 802.11ac)

Abstract: This talk will provide an overview of Transmit Beamforming (TxBF) in the WiFi IEEE 802.11ac standard along with the potential gains with Multi-user MIMO configurations. The talk will dive into the frame structures, messages and computations required to close the TxBF link. The second part of the talk will focus on the role of High-level synthesis (HLS) in order to scale and build TxBF HW solutions over a wide range of antenna configurations (i.e. 1x1, 2x2, 3x3 and 4x4) and multiple generation of parts.

Biography: David Garrett is an Associate Technical Director in the Office of the CTO at Broadcom. He has been recognized as a Distinguished Engineer within the company, and serves on the Broadcom Foundation University STEM Committee. David began his career at Broadcom in 2007 and has worked with many different business units within Broadcom to deliver high performance, low-power digital signal processing (DSP) cores. He was a part of Beceem Communications, a wireless startup developing 802.16e WiMax chipsets. Prior to Beceem, he was with Lucent's Bell Labs Research Wireless Research Laboratory, as an expert in both forward error correction technology as well as Multiple-input Multiple Output (MIMO) wireless signal processing. He serves as a technical expert on Broadcom's internal patent review committee, and is on the organizing committee for the International Symposium on Low Power Electronics and Design (ISLPED) as the TPC Co-chair. He has 40 patents, 21 conference and journal papers, and has co-authored a book chapter on MIMO receiver design. David received a B.S. and Ph.D. in Electrical Engineering from the University of Virginia, and an M.S. from the University of Vermont.
