A novel combination algorithm based on chip equalizer and multi-path interference cancellation
Zhan Gao, Qihui Wu, Jinlong Wang · 2005
High-speed packet transmission is an important characteristic in the 3/sup 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 multipath interference cancellation together. The algorithm (PC-LMMSE) is proposed based on 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.
