| 摘 要： | 通过插入导频估计出信道的频率响应是信道估计技术的一项重要内容，目前常用的基于导频符号的信道估计算法中，导频插入方案有块状、梳状和星状分布3种，它们各自有其缺陷，限制了其应用的环境.笔者结合已有的这3种导频分布结构的优势，提出了一种新的基于斜状导频分布结构的算法，该算法不仅频谱利用率高，算法性能好，而且大大降低了运算的复杂度.

| Abstract: | Estimation of channel frequency response through insertion pilot is an important content of the channel estimation technique.At present,there are three kinds of pilot insertion plans:messive,honeycomb and astooid distribution eaching having its flaw respectively,which limits the application environment.This article proposes one kind newly based on the diagonal pilot structure algorithm.The new algorithm has high spectrum efficiency and good is algorithm performance;moreover,it reduces the arithmetic complexity. |
