Hopping-frequency communication is often used in military Satellite Communication(SATCOM) systems,which may lead to the difficulty in coherent detection Phase Shift Keying(PSK) signals unless many reference symbols are added to aid the phase estimation of the received signals.
军事卫星通信系统中很多情况下采用跳频通信,这就导致PSK的相干检测比较困难,通常使用增加参考符号来对接收信号的相位进行估计。
