A MIMO-OFDM Testbed for Wireless Local Area Networks

Abstract

This paper describes the design steps and final implementation of a MIMO OFDM prototype platform developed to enhance the performance of wireless LAN standards such as HiperLAN/2 and 802.11, using multiple transmit and multiple receive antennas. We present the design methodology, including cross-validation of the Matlab, C++ and VHDL components, and the final demonstrator architecture. We highlight the increased measured performance of the MIMO testbed over the single-antenna system
