| Abstract(in English) | In this paper, we proposed a new peak reduction method applicable to OFDMA systems, in which a user uses some frequency bands in all system bands, by using iterative peak reduction method for broadband wireless communications. The proposed method separates the system band into a information signal band and a peak-reduction signal band, and generates peak-reduction signals in the peak-reduction signal band by using iterative signal processing. Moreover, low level peak-reduction signals are generated in the information signal band to improve peak-reduction performance. The results by computer simulation show that proposed method can achieve the PAPR reduction of 3 to 4dB with almost no degradation of BER performance. |
