| Abstract: |
| 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. |
