Abstract(in English) | This paper examined the adaptive array which suppressed only the delayed signals out of the guard interval in the OFDM system. The proposed method targets the OFDM system with the constant amplitude on signal point of the subcarrier. In this case, the frequency characteristic does not depend on modulation when the delayer signal wave within the guard interval. The proposed method suppresses the delayed signal out of the guard interval by using this frequency characteristic. This method does not need a known reference signal and estimation of channel characteristic. However, there is a problem in the convergence characteristic because the proposed method performs weight control with a blind processing. For this problem, this paper also proposes the method of emphasizing the error to reference signal. The BER characteristic is evaluated in the static multipath channel and Rayleigh fading channel. The results show that the proposed method suppresses the delayed signals out of the guard interval effectively. |
