Performance Analysis of Beamforming for MIMO OFDM With BICM
Overview This paper shows and quantifies both analytically and via simulations that the use of channel knowledge at the transmitter, the technique known as beamforming, achieves the maximum diversity in space when the best eigenmode is used (single beamforming). Furthermore, the authors investigate beamforming in conjunction with next generation Wireless Local Area Networks (WLANs). It is known that the widely used technique in WLANs, Bit Interleaved Coded Modulation (BICM) with Orthogonal Frequency Division Multiplexing (OFDM), can achieve the maximum frequency diversity order that is inherited in the channel. The authors show that the combination of BICM, single beamforming, and OFDM also leads to the maximum diversity order in space and frequency domains.
