碩士 === 元智大學 === 電機與資訊工程研究所 === 87 === This thesis presents a novel approach for the performance improvement in a CDMA wireless system by employing a covariance adjustment adaptive array to solve the near-far problem. Specifically, it is combining additional covariance adjustment modules and a multi-weight LMS adaptive array in a base station for co-channel interference cancellation to a large number of system users. Following the previous results and the preparation for the actual implementation, we conduct the real-time simulation of the proposed system in various operation conditions. The results show that our system indeed achieves a far better performance than other comparable systems do.
