Patent ID: 7020451

Claim:
A radio transceiver system for communication of signals occurring in multiple channels in a frequency band, the system comprising: a radio transceiver that downconverts energy in the frequency band including energy in the multiple channels and produces a baseband receive signal representative thereof, and that upconverts a plurality of transmit signals each to be transmitted in a corresponding one of the multiple channels in the frequency band; an analog-to-digital converter (ADC) coupled to the radio transceiver that converts the baseband receive signal to a digital receive signal; a digital-to-analog converter (DAC) coupled to the radio transceiver that converts digital transmit signals to analog transmit signals for upconversion by the radio transceiver; and a baseband signal processing section coupled to the ADC and to the DAC that baseband demodulates the digital receive signal to recover multiple receive data associated with corresponding channels in the frequency band and that modulates multiple transmit data to produce digital transmit signals for processing by the DAC and transmission by the radio transceiver in corresponding channels in the frequency band, wherein the baseband signal processing section performs baseband modulation according to a communication protocol for each of multiple transmit data for transmission by the radio transceiver in corresponding channels in the frequency band, and performs baseband demodulation according to the communication protocol of the digital receive signal representing receive signals for corresponding channels in the frequency band, to thereby simultaneously support multiple channels in the frequency band of the same communication protocol.
