ABSTRACT:
A diversity receiver includes N number of Fourier transform circuits, N number of channel estimators, N number of match filters, N number of soft demappers, a combination/selection unit, and a channel decoder. The diversity receiver merges the square of the absolute value of estimate channel frequency response and transmission data into a demodulation signal and then outputs the demodulation signal by means of the match filter.
