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 2):
Receiver apparatus as set forth in  claim 1 , wherein said means for serially arranging said first set of QAM symbols in each COFDM symbol in a first prescribed spectral order and said means for serially arranging said second set of QAM symbols in each COFDM symbol in a second prescribed spectral order are such as to accommodate the spectral orders of the first and second set of QAM symbols being similar to each other in said selectively received radio-frequency COFDM signal, which provides uniform frequency diversity between QAM symbols in said first and said second sets of QAM symbols that convey similar FEC-coded data.
