It also give an improved method for PLL (phase locked loop) to extract coherentcarrier.
本文还对相干载波提取中的锁相环提出了一种改进方法。

Carrier synchronization is a key technique in the coherent -demodulation of PSK signals and it is directly related to the specification of demodulation.
载波同步是PS K信号相干解调中的一项关键技术，它直接关系到解调的指标。

Non coherent demodulation for 2PSK detects relation of carrier wave phase of the interval symbol by the (half period of carrier wave) delay and the adder, then the data is demodulated.
