Abstract
A channel estimation method for TD-SCDMA system includes: sending midamble data to channel estimator and estimating the serving cell and adjacent cell channel response; calculating the interference cell number and setting the iteration number for interference cancelation; providing a channel response to a channel noise-suppression module that outputs a suppressed channel response; applying adaptive iterative interference cancelation. The invention solves the difficulty about the estimation of channel in multicell system, thus improving the estimation accuracy and the system capacity.
