  • Diversity receiver
    Patent number: 7623591
    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.
    Type: Grant

  • Diversity receiver
    Publication number: 20080285674
    Abstract: A diversity receiver includes N number of Fourier transform circuits, N number of channel state estimators, N number of channel equalizers, N number of soft demappers, N number of noise power estimators, N number of multipliers, a combination/selection unit, and a channel decoder. The noise power estimators and multipliers provided in the diversity receiver generate individual channel weights for each channel, which serve as background noise information for the channel decoder.
