MIMO Beamforming for Multi-User System in Frequency-Selective Fading Channels

摘要

In this paper, we proposed multiple-input multiple-output (MIMO) beamforming for a multi-user system in frequency-selective fading channels, The Maximum Signal-to-Noise (MSN) method, where noise includes the additive white gaussian noise (AWGN) and interference signals, is regarded as a criterion to determine the transmit and receive weight vectors. Maximizing the output signal-to-noise and Interference ratio (SINK) has been considered to evaluate improvement in performance of the proposed system. The advantage of the proposed system includes reduction in configuration and increase in channel capacity. Results of computer simulation are presented to verify our analysis.
