同步CDMA系统的一种次最优的2维Rake接收机

A sub-optimal 2D Rake receiver for S CDMA

本文研究自适应阵列与多用户接收相结合的检测技术 ,给出了同步CDMA的一种次最优 2维Rake接收机。通过计算机仿真 ,与传统的 2维Rake接收机作了比较 ,说明这种接收机克服了传统接收机具有的空间相关效应和远近效应。文中最后分析了联合的自适应阵列和多用户接收在蜂窝环境下的容量 ,指出两种技术的结合能弥补各自的缺陷 ,从而大大提高系统的容量。

This paper studies the detection by combining the antenna arrays and multi user receiver A suboptimal 2D Rake receiver for synchronous CDMA is proposed The performance,compared with the conventional 2D Rake receiver using computer simulations,shows that this receiver avoids the spatial correlation effects and farnear effect which conventional receiver owns Finally,we analysis the capacity of joint antenna array and multiuser receiver in cellular environment and conclude that the joint two technology can make up respective limitions
