Abstract
A channel estimation method is provided. The method includes the following steps of: receiving an input symbol of an input signal and obtaining several pilot channel gains through calculation; executing an operation of interpolation on the pilot channel gains by a Wiener filter to obtain several data channel gains through calculation; calculating an adaptive alteration for the first and second multi-path statistical characteristic parameters according to the data channel gains and the pilot channel gains, and accordingly having the first and the second multi-path statistical characteristic parameters adjusted; generating an updated Wiener filter according to the adjusted first and second multi-path statistical characteristic parameters to execute an operation of channel estimation on a next input symbol of the input signal.
