载波同步对通信系统起到重要作用。实际的通信系统中可能存在时域相关噪声，其影响常规载波同步的性能。对此，利用噪声的时域相关统计特性，并在噪声相关矩阵特征分解的基础上，进行分析推导，得到一种改进的载波同步方法。仿真结果验证了所提改进方法是有效的。

Carrier synchronization plays important role in communication system. In real system, the additive noise may be time-domain correlated, which affects the performance of normal carrier synchronization. To dimin-ish the effect, the statistical time-domain correlation characteristic of noise is used, and through theoretical de-duction based on eigen-value decomposition of the correlation matrix, an improved carrier synchronization method is attained. Simulation results show that the proposed method is valid.
