Spatio-temporal parallel processing and complexity reduction for OFDM multiple antennas system

In this paper, we propose combining spatio-temporal signal processing, OFDM technique and multiple antennas system for high data rate and high performance communication. In order to perform real time processing, we also propose a complexity-reduced QR-beamformer for VBLAST algorithm and parallel processing systolic array architectures. Simulations show that significant performance gains of the proposed system can be realized in terms of lower bit error rate and higher data transmission rate. Numerical evaluations also show that the proposed method and architectures can significantly save computational efforts and operational time
