OPTIMIZATION OF BEAMFORMING TECHNOLOGY FOR COGNITIVE SPATIAL ACCESS IN MILLIMETRE WAVE

O.J Femi-Jemilohun, Stuart Walker

Abstract

The allocation of 60GHz spectrum for WLAN has made the quests for gigabit data rates delivery to the end users possible in the wireless communication domain. The peculiar propagation characteristics in the millimetre wave can be exploited for improved system capacity. In optimizing beamforming techniques, a weight vector that minimizes a cost function is determined. The most commonly used optimally beamforming techniques or performance measures (cost function) are Minimum Mean Square Error (MMSE), Maximum Signal-to-Noise ratio (MSNR), and Minimum (noise) Variance (MV). A matlab based MVDR (Minimum Variance Distortion Response) and Phase-Shift Beamforming algorithms are proposed in this paper as means for cognitive spatial access in the millimetre wave band to enhance the signal of interest (SOI), with the suppression of interferences. Simulation results reveal that MVDR outperforms the Phase-Shifts in interference limited spatial multiple access (SMA) systems.
