    • 本篇論文主要是針對於大型MIMO系統提出新的BP技術，在這新的BP中我們加入了precoding，解決傳統BP可能無法收斂與BER表現不佳的問題，模擬顯示本論文所提出的新的BP技術在BER的表現上遠遠超過其他現有文獻所提出的BP技術

    This thesis propose a novel belief propagation algorithm for large MIMO systems. Unlike the conventional BP algorithm which may not converge or provides high BER performance, the proposed algorithm based on precoding offer the near-optimal BER performance. The simulation results shows the proposed BP algorithm provide much better BER performance than the conventional one.
