| Abstract(in English) | A new spread spectrum communication method, which shows good PAPR performance, has been proposed. The proposed method uses FSK as primary modulation and phase rotation sequences as a spread spectrum sequence. Since the FSK signal has constant amplitude and signal spreading by means of the phase rotation sequence does not change the amplitude of the signal, the PAPR performance of the proposed method can be better than that of a conventional direct-sequence spread spectrum (DS-SS) method. Hence, the proposed method is able to improve the efficiency of non-linear amplifiers, and is expected to be very useful for power-limited satellite communication applications. In this paper, we present the outline, basic characteristics, configuration, and experimental results of the prototype modem, which has been newly developed to apply the above method. |
