Abstract :
In this paper, we propose two receiver algorithms, digital matched filter (DMF) and zero forcing (ZF), to enhance performance of STBC under frequency selective channel in TDD-CDMA system and present the analysis of the interference of them. At the end of this paper, simulation results and conclusion show that ZF is better than DMF in terms of performance and robustness.
