Per-survivor processing sequence detection for DS/CDMA systems with pilot and traffic channels

Abstract

A per-survivor processing (PSP) sequence detection receiver is proposed for DS/CDMA systems with pilot and traffic channels. The proposed receiver jointly estimates channel parameters and data symbols from pilot and traffic channels, and is derived by modifying the receiver in [1]. As a result, the new receiver can outperform the receiver in [1] in exchange for additional computation. Computer simulation results demonstrate the advantage of the proposed receiver over existing ones.
