摘要

本文介绍了cdma2000系统中计算和消除导频信号干扰的一种有效方法

并将其应用于单个和多个蜂窝小区的环境中.仿真结果表明

采用本方法的RAKE接收机既可以保证信道估计的精度

合并接收到的多径信号;又可以有效地消除由导频信号所引入的多址干扰

使得系统性能得到较大程度的提高.同时

符号速率上的导频干扰抵消运算大大降低了实际系统中硬件实现时的复杂度.

Abstract

An effective method of calculating and eliminating the multiple-access interference (MAI) introduced by the pilot signal in cdma2000 systems is presented in this paper.Its applications to single-cell and multi-cell environments are also described.Computer simulations show that the RAKE receiver with the proposed pilot cancellation scheme can not only ensure the accuracy of channel estimation and combine separable multi-path components but also effectively eliminate the MAI due to the pilot signal.So the system performance is greatly improved.Besides

pilot cancellation at symbol rate leads to relatively low hardware complexity in its implementation for practical systems.
