| 摘 要： | 本文提出循环类分解和等模类分解法，解决了Ｍ－ＱＡＭ系统中载波相位估计量［１］的统计分析问题。证明了载波相位估计方差除了与加性噪声有关外，它与载波归一化频差的平方成正比；与码型噪声有关，同时，本文的结果简化了对码型噪声的分析模型。

| Abstract: | In this paper, the decomposition method of circular class and equal modulus class is presented. The problem of statistical analysis of carrier phase estimation in M-QAM system is discussed. It is proved that the variance of carrier phase estimate is a direct ratio of square of carrier regular frequency difference and is dependent on the selfnoise besides the additive noise. Meanwhile,the result of this paper simplifies the analytical model of selfnoise. |
