The principle of time delay estimation is presented and cross correlation method is used to acquire time delay of two-channel signals. 介绍了时延估计的原理,并对两路信号互相关的方法来测量信号的时延。 paper.pet2008.cn 2. The result
Subsequently, the analytical cross-correlation method is applied to determine the group delay and phase shift, which only requires measurements at two adjacent positions. On this basis, the phase velocity value at each frequency is calculated from the relations between the propagation distance, group ...

direct peak detection method always produces poor results, especially in the systemwith a low signal-to-noise ratio (SNR). In previous works [4]–[6], many demodulation algorithms have been proposed, such as centroid detection algorithm (CDA) [4], least squares algorithm (LSQ) [5], and ...
