Abstract

A promising technique for significantly increasing the bandwidth efficiency and wireless transmission capacity is space division multiplexing. Vertical Bell Laboratories Layered Space-Time (V-BLAST) is one technique which exploits the rich scattered wireless channel by using multiple transmit and receive antennas. In this paper, we extend the VBLAST formulation to a multicarrier system devised for a more general frequency selective and time varying channels. In particular, we apply the spectral efficient Orthogonal Frequency Division Multiplexing (OFDM) transmission technique to V-BLAST with Reed-Solomon coding. This technique achieves high speed wireless data services and makes the system more robust against Inter Symbol Interference (ISI). The proposed system performance is evaluated and investigated over time dispersive and multipath fading channels. The system maximum delay spread tolerance is also studied.
