摘要
当采用相关法估计时间延迟时,多径时延的分辨率受到相关函数主(?)宽度的限制。本文将最大熵谱估计方法中的Burg算法和Marple算法引入不可解的多径时延估计,可以得到较高的时延分辨率。给出了原理和性能分析以及计算机模拟的结果。
Multipath time delay estimation is constrained by the width of the signal correlation function when using correlation method. This paper obtains a high resolution tune delay estimation by introducing Burg and Marple algorithm of the maximum entropy power spectrum estimation to non-resovable multipath time delay estimation. The principle, the performances and the results of computer simulation are given.
