Abstract
A multi-code-set channel estimation method in a time-slot CDMA system having steps of: A. performing uni-code-set channel estimations and obtaining channel estimation result; B. extracting a maximum interference tap from the channel estimation result; C. reproducing interference components suffered respectively by response signals corresponding respectively to the plurality of code-sets from the maximum interference tap; D. canceling the interference components, and obtaining a pure channel estimation result of a signal corresponding to each code-set; E. determining whether a predetermined number of iterations has been performed, if so, outputting the result of each uni-code-set channel estimation; otherwise, taking the pure channel estimation result of the signal corresponding to each code-set as the channel estimation result of the code-set to be processed in the next iteration, and returning to step B. Due to the present invention, a multi-code-set joint channel estimation with high performance can be implemented simply and effectively.
