基于软件无线电的WCDMA仿真平台

本文介绍了一种关于3G的仿真平台的研究、开发和验证。结合软件无线电思想，参照3GPP协议，在COSSAP软件包中搭建起一个具有通用结构的、基于第三代WCDMA、FDD方式的下行链路物理层的仿真平台，并进行了Turbo编译码、RAKE接收机等3G关键技术的研究和单路数据业务、单路话音业务及多业务复用时系统性能的仿真验证。仿真结果与相关文献拟合得较好，结果证明可以把它作为进一步研究软件无线电中关键技术的基础平台。

Simulation Platform for WCDMA Based on Software Defined Radio

This paper presents a new simulation platform for 3G (the third generation mobile communication). Combined with concept of Software Defined Radio(SDR) and complied with 3GPP proposal, firstly, the authors built up a general structure platform of downlink physical layer based on 3G WCDMA (FDD) in COSSAP software package, then studies such key technology of 3G as Turbo encoders and decoders, RAKE receivers. The authors also perform some system simulation research on the platform such as single data service, single voice service, multiple services and so on. The simulation result is similar to relevant documents. The results verify that it can be applied as a basic platform to do further research on the key technology in SDR field.
