| Abstract(in English) | We consider to apply orthogonal frequency division multiplexing (OFDM) schemes to satellite communications systems. OFDM schemes have advantages of their high-speed data transmission and their high frequency efficiency. On the other hand, a major drawback of OFDM is its high peak power. In satellite communications systems, since nonlinear amplifiers are used, OFDM schemes are difficult to be applied due to their high peak power characteristics. Therefore, we consider to apply phase modulated OFDM schemes. Because of this, an OFDM/PM scheme for generating a constant envelope signal by secondary modulation an OFDM signal with PM investigate. However, its bandwidth could be spread. In this paper, we apply cyclic shifted sequences (CSS) method as peak power reduction technique of OFDM signal in order to reduce the bandwidth. We evaluate the effect of Bandwidth Reduction in OFDM/PM scheme with CSS method by computer simulation. Simulation results show that the Bandwidth can be reduced without the BER (bit error rate) performance deterioration. |
