Abstract:
Receivers for coded orthogonal frequency-division multiplexed (COFDM) signals conveying the same coded data both in lower-frequency and upper-frequency sidebands thereof. Apparatus for performing a complex synchrodyne of COFDM signal to baseband is followed by apparatus for extracting the COFDM subcarriers of the lower-frequency and upper-frequency sidebands of the COFDM signal from the in-phase and quadrature-phase results of the complex synchrodyne. The COFDM subcarriers of the lower-frequency sideband as converted to baseband are supplied to apparatus for demodulating and demapping those subcarriers to recover a first set of coded data. The COFDM subcarriers of the upper-frequency sideband as converted to baseband are supplied to apparatus for demodulating and demapping those subcarriers to recover a second set of coded data. A diversity combiner combines the first and second sets of coded data for subsequent decoding.

Claim (Index 12):
Receiver apparatus as set forth in  claim 11 , comprising:\n a computer connected for computing the discrete Fourier transform of said successive samples of said baseband single-sideband COFDM signal, said computer constituting said means for developing first and second sets of QAM symbols; a frequency-domain channel equalizer for said first and second sets of QAM symbols said computer computes from each of said successive samples of said baseband single-sideband COFDM signal; a first parallel-to-serial converter connected for receiving in parallel each equalized said first set of QAM symbols and for supplying each equalized said first set of QAM symbols seriatim to said means for demapping said first set of QAM symbols as thus serially arranged, said first parallel-to-serial converter constituting said means for serially arranging said first set of QAM symbols in each COFDM symbol in said first prescribed spectral order; and a second parallel-to-serial converter connected for receiving in parallel each said second set of QAM symbols said computer computes from a respective one of said successive samples of said baseband single-sideband COFDM signal and for supplying each said second set of QAM symbols seriatim to said means for demapping said second set of QAM symbols as thus serially arranged, said second parallel-to-serial converter constituting said means for serially arranging said second set of QAM symbols in each COFDM symbol in said second prescribed spectral order.
