| Abstract(in English) | This paper proposes a Multi-Carrier KMA (MC-KMA) adaptive array for an OFDM system. With the frequency-domain data. after FFT processing. this algorithm operates to receive the desired wave (synchronized signal) and delayed waves within a guard interval while suppressing other waves. Using estimated sets of delay time and amplitude of all waves within a guard interval, this algorithm firstly derives the transmission response in each subcarrier and secondly performs minimization of the error between the transmission response and the received subcarrier signal. In the obtained transmission response, however. frequency selective fading may cause some subcarrier components to have zero amplitude, which has a had effect on the subsequent equalizer. For this problem, it is shown that the zero amplitude is easily avoidable by putting threshold level in the transmission response. It is one of the advantages of this system. |
