Low-Complexity Transceiver Design for MIMO Broadcast Systems

摘要

In this letter, we propose a low-complexity transceiver design for multiple-input multiple-output (MIMO) broadcast systems based on channel inversion, QR decomposition, and successive interference cancellation technique. Furthermore, an effective power loading scheme is developed to optimize the bit error rate (BER) performance. Analytical and simulation results show that the proposed design can achieve comparable performance with existing schemes while offering much lower computational complexity.
