摘要 符号同步是全数字接收机中必须要完成的一项重要工作。找出一种算法相对简单,计算量小,估计精度高的符号同步方案,对于QAM信号的解调是十分有意义的。文章在对最大平均功率算法进行分析的基础上,提出一种联合估计方法,并对该方法进行了算法仿真,并进行了性能分析。 Symbol synchronization is one of the most important processes that all digital receivers have to achieve. It is of great significance to find an algorithm which is simple, small in calculation and high in estimation precision for QAM signal demodulation. Based on the maximum mean power estimate algorithm, this paper describes a united estimation algorithm： and analysis on capability of the algorithm is also presented.
