对蜂窝系统干扰抵消的概述

未来干扰受限的蜂窝网络将越来越受到人们的青睐，尽管在过去20年里对干扰检测接收机的研究和用多用户技术提高性能，今天的接收机仍只能处理图像背景噪声的干扰。将讨论当前和将来的发展趋势，增加多用户接收机对同时能检测大量异步用户的上行链路及用户被预定和正交化的下行链路的需求和可行性，对最近对干扰抵消的研究突破和为将来多用户接收机集中系统水平考虑作出了总体概述。

Counteraction for inferference of cellular system

Although the interference and detecting receiver is studied on,and the performance for multiple user technology is improved in the 20years,people devote much attention to the limited interference cellular system increasingly.The receiver can only process the interference in the noise of image background.This paper discusses on the trend and analyzes the demands and feasibility of up link and down link.It summarizes a breakthrough of the interfevence counteraction and the thought of the multiple user receiver system.
