说明：  看重讨论了数字接收机中载波同步环的一种设计方法,详细分析了从模拟域到数字域的转化过程，并以16QAM数字接收机载波同步环为例给出了相应的结论
(Seriously discussed the digital receiver carrier synchronization in a ring design methodology, a detailed analysis of the domain from analog to digital domain of the transformation process, and 16QAM digital receiver carrier synchronization loop as an example the corresponding conclusions)
