Patent ID: 7885178

Claim:
A quasi-parallel wideband receiver to receive signals that are transmitted simultaneously on subchannels of a wideband channel that comprises a plurality of subchannels, the quasi-parallel receiver comprising: a plurality of subchannel low-pass filters, each associated with one of the subchannels; a subchannel filter selection switch having a plurality of outputs, wherein each output is coupled to an input of one of the subchannel low-pass filters, the subchannel filter selection switch is to select a subchannel low-pass filter associated with one of the outputs during a filter-input sampling interval to provide an analog baseband signal to the selected one of the subchannel low-pass filters; and a heterodyne frequency generator to provide one of a plurality of heterodyne frequencies to convert a radio-frequency signal received within a selected subchannel to the analog baseband signal, wherein the subchannel low-pass filters are to accumulate signal information from an associated one of a plurality of subchannels during the filter-input sampling interval that is to occur at least as often as an inverse of a bandwidth of a subchannel.
