Abstract:
1. A wireless reception system, comprising: a reception module for receiving 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 for generating a plurality of candidate channel effects according to the at least one input signal; an equalization module for performing 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 for selecting 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, wherein the reference signal is a transmission parameter signaling (TPS) having undergone differential binary phase shift keying (DBPSK), and the selection module selects the equalization result having a smallest imaginary part from the equalization results as the optimal equalization result most similar to the known signal.
