Abstract

This article presents a performance evaluation of various multi-antenna concepts based on OFDM for wireless LANs. The studies are based on state-of-the-art measured channel data in the 5 GHz band. The investigated techniques include: spatial multiplexing (BLAST), space frequency trellis coded modulation, their concatenation, turbo bit interleaved coded modulation and turbo space frequency trellis coded modulation. The studies aim to assess the MIMO concepts for future high speed WLANs.
