Abstract(in English) | As for the communication that uses high carrier frequency, for example, satellite communications etc., phase noise cannot be disregarded. To obtain large transmitting power, the power amplifier is operated by nonlinear amplification like C-class amplifications. But it causes spectrum spread when operated at the saturation level to output the maximum power. So as to keep the effect of the band-limitation, it is necessary to carry out constant envelope technique for modulated waveforms. Therefore, this paper presents a BPSK system to subtract the phase noise with a pilot signal. Furthermore, it is shown not to cause out-of-band spectrum by constant envelope technique even when nonlinear amplifier is used. The effect of this system is verified by computer simulation. |
