摘要

LTE-A(Long Term Evolution Advance)為3GPP（3rd Generation Partnership Project）所制訂出的第四代行動無線寬頻技術之一，關鍵技術如多重輸入多重輸出(multiple input multiple output, MIMO)系統可以增加傳輸容量(capacity)和獲得空間增益(spatial diversity gain)，若能搭配適當的訊號偵測演算法必能有效地提升頻譜使用效率，本論文主要針對LTE-A MIMO系統使用不同偵測演算法在正規化都普勒環境下之效能、複雜度還有各種偵測演算法在高速移動下通道之快速變化和多重路徑下產生符際干擾效應之效能進行研究。本論文共模擬分析了常見的偵測演算法並加入了LTE-A的code matrix和本實驗室所提出之低複雜度SIC演算法之應用等 。

Long Term Evolution Advance (LTE-A) is one of the fourth-generation wireless mobile broad band technology which was developed by 3GPP (3rd Generation Partnership Project). In this thesis, the features and techniques of LTE-A system are first illustrated. The multiple-input multiple-output (MIMO) antenna systems can increase the transmission capacity and the spatial diversity gain, if with the appropriate signal detection algorithm will be able to effectively improve the efficiency of spectrum. The much better performance detection algorithm is often accompanied much higher complexity problem. In this thesis, we analyzed the performance and the complexity of the MIMO systems using different detection algorithms under exponential channel. This thesis analyzed simulation of the traditional linear detection algorithm and low complexity SIC algorithm combined with LTE-A code matrix system.
