摘要
对于无线通信网络而言,最关键也是最困难的是无线信号的处理,它必须考虑包括信号质量、覆盖范围、数据传输速率、网络容量、保密性等诸多因素。WCDMA网络的无线信号处理在其射频子系统中完成,文章在研究3GPP2规范的基础上总结了射频子系统硬件要实现的功能,提供了实现这些功能的总体设计方案,可以为厂商进行WCDMA射频子系统设计时提供参考。按照这一方案设计出的试验网经过建网实地测试,得到的参数基本达到规范的要求。
For wireless network, the most important and difficult part is wireless signal. It must take into consideration factors such as signal quality, cover range, transmission speed, network capacity and signal＇s safety. After studying the criterion of 3GPP2, this article summarizes the functions of hardware in WCDMA RF sub-system and offers a general plan for its design, which can serve as a reference for companies developing the system. The pilot network based on this plan fulfils all the requirements of the criterion.
