用法和例句

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。

To combat frequency offset due to Doppler shifts or local oscillator drifts,a novel approach to frequency offset estimation based on phase reference symbol is presented.

为解决正交频分复用(OFDM)系统中由多普勒频移和本地晶振偏移造成的载波频偏,提出了基于相位参考符号的频偏估计方法。
