WIRELESS RECEPTION SYSTEM AND METHOD FOR ESTIMATING CHANNEL EFFECT THEREOF

摘要

A wireless reception system includes a reception module, a preliminary estimation module, an equalization module and a selection module. The reception module receives a reference signal and at least one input signal transmitted via a multipath environment. The reference signal is associated with a known signal unaffected by the multipath environment. The preliminary estimation module generates a plurality of candidate channel effects according to the at least one input signal. The equalization module performs equalization on the reference signal according to the candidate channel effects to generate a plurality of equalization results. From the equalization results, the selection module selects an optimal equalization result that is most similar to the known signal, and selects the candidate channel effect corresponding to the optimal equalization result to represent the multipath environment.

1. A wireless reception system, comprising:
a reception module, configured to receive a reference signal and at least one input signal transmitted via a multipath environment, wherein the reference signal is associated with a known signal unaffected by the multipath environment; a preliminary estimation module, configured to generate a plurality of candidate channel effects according to the at least one input signal; an equalization module, configured to perform an equalization process on the reference signal according to each of the candidate channel effects to generate a plurality of equalization results; and a selection module, configured to select an optimal equalization result most similar to the known signal from the equalization results, and to select the candidate channel effect corresponding to the optimal equalization result to represent the multipath environment.
