| 摘 要： | 在扩频系统中,多用户检测是一种能够有效抑制多址干扰和远近效应的技术手段。本文提出了一种在导弹通信环境下的多用户检测方案。在上行链路,由于基站同时对多个导弹发送控制信息,并且发给各个导弹的信号能量基本相等,因此采用部分并行干扰对消算法;而在下行链路,由于导弹的随机接入,信号存在异步通信和能量不均的情况,所以我们采用基于卡尔曼滤波的盲多用户检测算法。

| Abstract: | Multiuser Detection is an efficient way of suppressing Multiple-access Interference(MAI) and Near-far resistance. In this paper,we propose a design of multiuser detection project for missile communication. In uplink,the base station sets control information to all the missiles instantaneously and all the powers of signals are basicly equal to each other,so we use partial parallel interference cancellation to satisfy the communication; In downlink,the missile connects randomly,the powers are not equal and si... |
