| Abstract(in English) | OFDM(Orthogonal Frequency Division Multiplexing) is to be used in the MMAC using 5GHz band systems as an effective solution under a multi-pass fading environment. The transmission diversity techniques for OFDM has been reported. However, such techniques reported can not completly compensate when received level at each sub-carriers is dropped because of multi-path fading. Therefore, the error rate performance・degrades compared with the case of AWGN(Additive White Gaussian Noise). In order to improve the performance better, it is proposed to control the gain of each sub-carrier at transmitter side for using transmission diversity. Then the receiver gets constant received level at eachsub-carrier. Moreover, concerning the peak power reduction, it is proposed to control the bound of the maximum gain according to the number of sub-carriers in each branch. |
