摘要

本論文主要目的在於評估“covariance adjustment adaptive array”應
用於 CDMA 無線通訊之系統效能。首先，我們提出完整的系統架構及進行
其可行性分析。然後，在系統效能評估方面，則採用Monte Carlo 的方式
，針對單一cell環境的single path及multiple path條件分別進行使用者
數目對bit-energy to interference plus noise ratio，以及系統天線
數目對系統效能的評估模擬，結果顯示與Qualcomm系統的效能相近，且在
某些情況甚至更優於它。另外，我們也嘗試推導系統效能之close form。

This thesis presents a modular covariance adjustment adaptive
array to reduce the co-channel interference in CDMA wireless
communications. First, we conduct the signal feasibility
analysis of the propose system. Then, Monte Carlo method
is used to evaluate the system performance under single
path and multiple path conditions within a single cell.
The results show that our system achieves a comparable
performance with, or in some situations even better than,
Qualcomm*s system.
