摘要

文章详细分析并推导得到了一类循环时延估计子的估计理论精度.在较高信噪比条件下(SNR＞-5dB)

仿真得到的估计精度与理论估计精度基本上是一致的

这说明了文章理论分析的正确性.在高斯白噪声和慢变化时变高斯白噪声两种噪声模型下对二相编码和四相编码信号的仿真实验表明

循环估计子估计性能确实要优于实际中经常使用的能量辐射计.

Abstract

The estimation accuracy for the cyclic time-delay estimator is discussed under the condition of white gaussian noise.Simulation results show that the simulation accuracy value is approximately the same as the theoretical one in the condition SNR＞-5dB

which indicates the exactness of the accuracy analysis.At the same time

under the condition of different background noise with WGN(White Gaussian Noise)and slowly time-variant WGN

simulation results based on biphase coding and quadriphase coding signals show that the cyclic estimator really performs better than the radiometor widely used in practice.
