| 摘 要： | 针对如何减少信道参数估计所需要的已知数据,文中在基于扩展算法的基础上,采用复指数基函数,通过获取部分信道响应数据来计算得到其他信道数据,从而减少信道的实际测量次数。重点研究了基扩展算法在不同基函数阶数和不同传输符号块采样点数的情况下,模型准确度的变化,给出了要使模型具有佳性能的参数设定方案。

| Abstract: | Based on the basis expansion algorithm,a complex exponential function is used to minimize the required data of channel estimation and obtain the other channel data response through the part of the channel that is calculated,thus reducing the number of actual measurement channels.The changes in model accuracy with different basic expansions and numbers of points in a transmission symbol block are studied and methods for achieving best performances are proposed. |
