Patent ID: 8064836

Claim:
A cognitive radio transceiver for dispersed wireless spectrum utilization, the transceiver comprising: a transmitter comprising a plurality of branches, each of the plurality of branches associated with one of each of a plurality of available dispersed bands in a dispersed wireless spectrum, each of the plurality of branches comprising; an upconverter for upconverting a received baseband signal to the carrier frequency associated with the branch; a transmitter amplifier for amplifying the upconverted baseband signal; and a transmitter bandpass filter for filtering the amplified, upconverted baseband signal; a transmitter combiner for combining each of the filtered, amplified, upconverted baseband signals from each of the plurality of branches into a combined signal; a transmitter for transmitting the combined signal over a single wideband antenna; a splitter for receiving the combined signal and for splitting the combined signal into a plurality of baseband receive signals, each of the plurality of baseband receive signals associated with one of each of the plurality of available dispersed bands; a receiver for receiving the plurality of baseband receive signals from the splitter, the receiver comprising a plurality of branches, each of the plurality of branches associated with one of each of the plurality of available dispersed bands in the dispersed wireless spectrum, each of the plurality of branches comprising; a receiver bandpass filter for filtering the baseband receive signal; a receiver amplifier for amplifying the filtered receive signal; and a downconverter for downconverting the plurality of amplified, filtered receive signal; a receiver combiner for combining the downconverted, amplified, filtered receive signals from each of the plurality of branches to recover the transmitted baseband signal.
