A) performing a single code-set channel estimation of the received signal of each code-set, respectively, to obtain an original channel estimation, and deciding whether the desired number of iterations is reached; if yes, outputting each single code-set channel estimate; otherwise, going to Step B; B) performing limited time decision for the original channel estimates, retaining taps of channel estimation that meet a certain condition, recovering the interference caused by the response of each code-set using the tap values; canceling the interference caused by the response of other code-sets in the received signal of each code-set to obtain a clean signal of each code-set; taking the clean signal of each code-set as the said received signal of each code-set; and returning to Step A. The method solves the channel estimation problem caused by response signals of multiple code-sets and improves performance of single-code-set channel estimation.
