摘要
分析了数字调制解调器载波同步技术，提供了计算机模拟测试的结果，并通过对两种不同鉴相器系统的性能比较，说明了把信号相位判断过程与信号解码过程结合，可使系统的性能得到明显改善。
A technique for Carrier synchronization of a digital modem is studied
and the results of computer simulations are given.Through comparison of two kinds of phase
estimator systems,it is shown that the combination of phase signal decision process and signal
decoding process will improve system performances obviously.
