摘要

本文建立了RAKE接收机中信道估计器的时域数学模型

以信道估计器输出的估计值与实际信道参数之间的相关系数作为衡量信道估计精度的技术指标

给出了信道估计精度与RAKE接收机误比特率之间关系的数学公式

并指出基于MMSE准则的信道估计方法即为连续导频模式下使得RAKE接收机获得最小误比特率的最优信道估计方法.

Abstract

The paper investigates channel estimation of RAKE receiver for DS-CDMA systems.The mathematical model of channel estimation with the assistance of a common pilot channel is established.The relationship between the accuracy of channel estimate and BER performance of RAKE receiver is presented in equation.Furthermore

the MMSE based channel estimation proves optimal in terms of BER performance of RAKE receiver.
