摘要
在有噪情况下,精确的时延估计是非常困难的。本文提出了一种新的时延估计方法,该方法有效地降低了噪声对时延估计的影响,和常用的自相关函数法相比较,这种算法明显降低了时延的估计误差。
Accurate time delay estimation is very important in very important in systems.This paper has proposed a new method to reduce the effect of noise on the estimation of time delay between different channels.Our new time delay algorithm will more considerably reduce the estimation error ompared with the conventional autocorrelation function method.
