Performance Evaluation of channel estimation in TD-SCDMA system

In previous B. Steiner channel estimation algorithm adopted in TD-SCDMA system, but there are some errors in estimated channel due to noise. In this paper, we evaluate the performance of Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) systems with channel estimation. In channel estimation we implement the channel estimation algorithm to equalize the channel and reduce the BER in the received signal. The Channel estimation is carried out at the receiver. In TDSCDMA, the uplink and downlink transmissions use the same frequency band for duplex transmission by using synchronized time intervals. The simulation result shows that the system performance is effectively increased.
