Patent ID: 7406141

Claim:
A receiver for demodulating a multi-tone, multi-band signal modulated using an inverse discrete Fourier transform to generate a signal having a plurality of tones spaced in frequency in a plurality of frequency bands, comprising: a plurality of demodulators, wherein: each of the plurality of demodulators is configured to demodulate a data signal having a different one of the plurality of frequency bands of the multi-tone, multi-band signal, and is configured to utilize a different sampling rate, each demodulator includes a discrete Fourier transform module and at least two of the plurality of demodulators have different discrete Fourier transform sizes, each demodulator includes a time equalizer coupled to the input of the discrete Fourier transform module, at least one of the plurality of demodulators receives a downsampled data signal, and the plurality of demodulators are configured to perform demodulation in parallel.
