Patent ID: 7649833

Claim:
A receiver configurable to operate in either a high-throughput mode or an increased-range mode, the receiver comprising: antenna selection circuitry to select more than one of a plurality of spatially diverse antennas to receive an orthogonal frequency division multiplexed (OFDM) symbol over one or more subchannels of a wideband channel comprising a plurality of the subchannels; a plurality of fast Fourier transform (FFT) circuitries each configured to generate frequency domain symbol-modulated subcarriers for one set of OFDM subcarriers, combining circuitry to combine corresponding frequency domain symbol-modulated subcarriers from the FFT circuitries to generate combined symbol-modulated subcarriers, wherein each subchannel of the wideband channel comprises a separate set of OFDM subcarriers, wherein in an increased-range mode when data is to be received on a single subchannel, each of the FFT circuitries is configured to generate frequency domain symbol-modulated subcarriers for the set of OFDM subcarriers associated with the single subchannel, and wherein in a high-throughput mode when data is to be received on each subchannel of the plurality of subchannels, each of the FFT circuitries is configured to generate frequency domain symbol-modulated subcarriers for a different one of the subchannels.
