摘要：
High-speed packet transmission is an important characteristic in the 3(rd) generation mobile communication system. In order to enhance the performance of the high-speed packet transmission in low spreading factor.. a new structure of chip equalizer (LMMSE-MPIC) is presented in this paper, which combines the linear chip equalizer with nonlinear multi-path interference cancellation together. The algorithm (PC-LMMSE) is proposed based oil pilot cancellation. Theoretic analysis and computer simulations show that LMMSE-MPIC is superior to conventional Rake and chip equalizer and effectively improves the performance of the WCDMA system in low spreading factor.
