Implementation of Channel Estimate in TD-SCDMA and Its Performance Analysis

In the uplink of TD-SCDMA,the data at the BS received from the antenna needs channel estimate and joint detection How to obtain rapidly and accurately the user′s channel impulse response is the key to the implement of algorithms behind If the channel estimate algorithm is too complicated and inaccurate,it must be a bad influence to the latter algorithms In this text,we have investigated Steiner estimator Steiner estimator is a simple and rapid algorithms for channel estimate and can jointly achieve all user′s channel impulse response at the same time and time slot This paper presents the computer simulation and performance analysis about the application of Steiner estimator in TDSCDMA
