碩士 === 國立暨南國際大學 === 通訊工程研究所 === 93 === Recently, CDMA communication assisted from smart antenna technique has received a great deal of attention due to the effective transmission capability. Although smart antenna and CDMA system have some advantages to improve the signal quality, the multiple access interference (MAI) is still a major problem. SEVERAL algorithms have been proposed to solve the problem, but the converging rate and the signal quality is still a tradeoff. In this thesis, we proposed a novel blind algorithm, which uses only the known PN sequence. Comparing to the conventional algorithms, simulation results show that the proposed algorithm has better performance in the terms of BER which is accepted to the wireless communication.
