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.
