Patent ID: 7583742

Claim:
A receiver for use in a multi-carrier transmission system, the receiver configured to receive a multi-tone signal modulated using an inverse discrete Fourier transform, comprising: a first demodulator configured to receive a first stream of data from the received modulated multi-tone signal, wherein the first stream of data has a plurality of tones spaced in frequency within a first frequency band and wherein the first demodulator includes: a first discrete Fourier transform module configured to utilize a first sampling rate, wherein the first sampling rate is optimized for the first frequency band; and a second demodulator configured to receive a second stream of data from the received modulated multi-tone signal, wherein the second stream of data has a plurality of tones spaced in frequency within a second frequency band and wherein the second demodulator includes: a second discrete Fourier transform module configured to utilize a second sampling rate, wherein the second sampling rate is optimized for the second frequency band, wherein the first sampling rate is different than the second sampling rate.
