摘要：
In order to enhance the performance of the high-speed packet transmission in low spreading factor, a new structure of chip equalizer RLS-MPIC (recursive least squares chip equalizer and multi-path parallel interference canceller) is presented, which combines the linear chip equalizer with nonlinear multi-path interference cancellation. The algorithm PC-MRLS (pilot cancellation modified recursive least squares algorithm) is proposed based on pilot cancellation. PC-MRLS suppresses the pilot interference and gains a good early decision result for MPIC. MPIC cancels the multi-path signal after equalization and improves the performance of the system. Theoretic analysis and computer simulations show that the new structure is superior to conventional Rake, chip equalizer and multistage multi-path interference cancellation receiver.
