摘要: 
隨著通訊技術的進步,提供高資料量以及高品質的傳輸已經成為近年來電信研究領域中最重要的挑戰。這篇論文主要著重在多輸入多輸出(MIMO)通訊系統下空時碼的訊號處理,我們將探討兩種具代表性的空時系統架構:BLAST和空時區塊碼,以及研究在多輸入多輸出下正交分頻多工(OFDM)與分碼多重接取(CDMA)收發機的結合設計。然後我們將比較這兩種空時系統在干擾環境下的效能表現,也會討論此空時系統架構在解碼時訊號處理的過程。

The development of wireless communication systems for high data rate and high link quality transmission between transmitter and receiver has become the most important challenge in the telecommunication research area. This paper proposes space time coding and signal processing for multiple-input multiple-output (MIMO) communication systems. We describe two representative categories of space-time systems, namely, the BLAST system and the space-time block coding system. We investigate the joint design of orthogonal frequency division multiplexing (OFDM) and code division multiple access (CDMA) transceivers under the MIMO system. And then we compare the performance of them in the rich scattering environments. We also discussed signal processing for decoding in space-time systems.
