一种时域信道估计的FPGA实现方法

The Implementation of Time_domain Channel Estimation on FPGA

在多径通信系统中,实时、准确地得到信道信息,是信道均衡和数据检测的关键。文中利用训练序列(PN序列)良好的循环自相关性,进行准确的时域信道估计,并在FPGA上实现。

In multipath communication systems,real_time and accurate channel information is the key point to channel equali- zation and data detection.This paper,by using the good cyclic autocorrelation of the training sequence（PN sequence）,estimates the channel time_domain response,and implement it in the FPGA.
