In land mobile communication, CMA(Constant Modulus Algorithm)has been studied to reduce multipath hading effect. By this method, the transmitted power is not used effcieiently since all the multipath components have the same information. To make use of received power efficiently, we propose a Blind Multiple Beam Adaptive Array. It has the following three feature points. First, we use CMA which can reduce the multipath fading effect to some extent without training signal. Second, LMS algorithm which can capture the multipath components which are separated from the reference signal by some extent. Third, we use FDF(Fractional Delay Filter)and TED(Timing Error Detector)loop which can detect and compensate fractional delay. As a result of utilizing the multipath components which is suppressed by CMA, the proposed technique acheives better performance than CMA adaptive array.
