| Summary: | 碩士 === 國立聯合大學 === 電子工程學系碩士班 === 94 === In this thesis, a novel blind receiver with enhanced multiple access interference (MAI) cancellation is proposed for CDMA systems. Specifically, an adaptive correlator is first constructed based on the linearly constrained minimum variance (LCMV) criterion to collect each multipath signal and suppress MAI blindly. A maximum ratio combiner is then utilized to coherently collect the correlator outputs. Finally, further performance improvement against the finite data sample effect is obtained by using a decision-aided scheme. Numerical results demonstrate that the proposed blind receiver with the similar performance as that of the MMSE receiver can achieve robustness against strong MAI and finite data samples.
