| Abstract(in English) | The performance of the adaptive OFDM modulation system deteriorate because of the delay for the feedback of channel state information from receiver to transmitter, when the channel varies rapidly. In this paper we propose the method using the instantaneous SNR prediction to compensate the delay and, based on the value, the optimum power of transmission and number of the constellation at each subcarrier is allocated to overcome that disadvantage.Moreover, we report on the result of the computer simulation done to show the effectiveness of the proposal technique. |
