Abstract:	區域多點分散式服務（Local Multipoint Distribution Service，LMDS），是一種點對多點（Point to Multi-point，PMP ）的固定式無線寬頻存取系統，並配合使用寬頻衛星來支援在不利LMDS 的傳播環境條件下時與衛星做鏈結。在使用多天線系統時，有著諸多技術可供使用。在此計畫中，我們將研究在此通訊環境中，評估適合之多天線傳輸模式。我們將考量干擾因素、頻譜效率、與錯誤率等來設計我們多天線傳輸之演算法，以增進系統整體效能。 Local Multipoint Distribution Service (LMDS) is a point to multi-point (PMP) fixed wireless broadband access system. A broadband satellite is employed to assist the communication link under some severe communication scenarios. There exists a couple of transmit modes for multi-antenna systems. In the project, we are focused on the determination in the transmission mode of the multiple antenna system under the various propagation environments. We aim to design the transmission scheme for the improvement of the system performance by considering the effect of interference, the spectral efficiency, and the bit error rate. 研究期間：9601 ~ 9612
