Estimation Performance for Cyclic Time-Delay Estimator
Wenli Jiang · Dianzi xuebao · 2004
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.
