Abstract

This paper investigates the joint detection method for TD-SCDMA system, and derives an improved approach to eliminate inter-symbol interference (ISI) in condition of multipath channel. Analysis for the received signals exhibits its characteristics of PARAllel profiles with LINear Dependencies (PARALIND) model. The proposed blind PALALIND algorithm utilizes no channel parameter for detection, and performs better with snapshots increasing. Simulation results indicate that its performance is quite close to space-time minimum-mean-square-error (ST-MMSE) and also robust in array error condition.
