摘要
将高阶统计理论应用于直接序列扩频信号的参数估计,提出了一种基于四阶累积量2-D切片的方法,该 方法能够同时估计载波频率和扩频码周期。计算机仿真结果验证了该方法的有效性。
This paper discusses the application of higher - order statistics to DS - SS signal parameters estimation. An approach based on fourth - order cumulant 2 - D slice is proposed, which can estimate the carrier frequency and the symbol period simultaneously . Computer simulation confirms its effectiveness.
