New Improved Channel Estimation Algorithm in TD-SCDMA System

B.Steiner channel estimation algorithm that is widely used in TD-SCDMA system is a low-cost algorithm. However, because of the affection of background noise , there are some errors of amplitudes and delays between the estimated implues responses and the real ones, which result in bad system performance. A gate method base on B. Steiner algorithm to reduce the affection of the noise is proposed. The simulation results show that this method is able to get a good performance without causing more algrithm complication.
