Abstract(in English) | In this paper, we focus on the temporal variation of the amplitude spectrum of received OFDM signal caused by long delay multipath wave over Guard Interval, we propose two improvement methods that suppress long delay multipath wave over Guard Interval and improve the bit error rate performance. One is the use of Short Pass Filter which cuts the delay waves over Guard Interval before averaging the amplitude spectrum for high-speed convergence of the weight vector of adaptive array. The other is the selective diversity which runs convergence algorithm from some initial weight vectors and demodulate data by using the weight vector of the largest amplitude spectrum in each subcarrier. We show the performance of improvement methods via computer simulations. |
