摘要
选用美国ELANIX公司1999年出品的SystemView系统仿真工具,依据系统原理,对WCDMA-FDD下行链路中信号的扩频、调制、传输及解调与合成进行了仿真分析.其中Rake接收部分的设计相对独立,分信号捕捉、延迟与合成3个步骤完成对多径信号的搜索与合成,以实现宽带系统下独特的信号接收,为系统的硬件实现奠定了良好的基础.
With the investigation and research, using the system simulation tools of SystemView, which is released in 1999 by ELANIX, simulation of the signal expansion, modulation, transfer and synthesis in the downlink base band system of WCDMA-FDD is done in this work. The Rake receiving part, however, is relatively independent. The unique signal receiving method in wide band system is realized through the searching and synthesis of the multi-route signals achieved after the three steps of signal＇s capture, delay and synthesis. This work also builds a good foundation for the hardware implementation of the WCDMA system .
