Abstract

In order to improve the research of TD-SCDMA system key techniques and provide necessary results for system level performance investigation, long-term and short-term average performance in link simulation is researched and compared. According to the TD-SCDMA protocols, a link simulation platform is set up using many important algorithms including channel estimation, joint detection, soft decision Viterbi decoding and so on. The emphasis is to evaluate the link level performance of DPCH 12.2 kbps under various multi-path fading channel environments.
