Realization Of Link Access And Decoding/De-multiplexing In WCDMA UE

Nowadays, as one of the mainstream 3G standards, WCDMA system has been widely used. In order to develop baseband chips, this thesis studies some issues of baseband processing in WCDMA UE, and accomplishes the development of the corresponding modules.The main work of this thesis includes:1. A realization approach is proposed of WCDMA random access procedure based on double AI check.2. An efficient automatic frequency offset compensation method is proposed based on CORDIC algorithm.3. Considering that software processing can address dynamically and smartly, a data sequence processing approach is proposed which simplifies WCDMA downlink decoding/de-multiplexing process.
