Title: Multiple-Input Multiple-Output Antenna Processing for Broadband Wireless

Date: November 08, 2002

Time: 3:00 pm

Location: GCATT Room 325

Abstract:
This talk considers multi-antenna wireless LAN transceivers enhanced with multiple-input multiple-output (MIMO) antenna processing for increased rate and reach. While multi-antenna techniques have existed for many years in complex and expensive communication systems, increased computational capabilities at a low cost are now making MIMO attractive for consumer devices. In this talk, we consider MIMO techniques coupled with Orthogonal Frequency-Division Multiplexing and IEEE 802.11a WLAN protocols. We discuss partitioning of modem functions among high-speed DSPs and hardware accelerators to yield a cost-effective yet flexible architecture. Based on the target architecture, we discuss a rapid prototyping platform used for development and analysis of a MIMO based WLAN chipset.

Biography:
Michael Polley received his B.S., M.S., and Ph.D. degrees in electrical engineering from the Massachusetts Institute of Technology in 1990, 1990, and 1996. In 1996 Mike joined the DSP Solutions R&D Center of Texas Instruments to help TI influence the DSL standards bodies and enter the ADSL market. From 1997 to 2000, Mike was manager of the ADSL research group developing DSP based solutions for evolving DSL standards. Since then, Mike has come unwired. He helped TI establish a fixed-wireless access chipset business, and then started the Wireless Broadband Architectures group where he is manager and distinguished member of technical staff.
