Patent ID: 8036315

Claim:
A method of operating a receiver that includes a software defined radio (SDR) multichannel receiver configured to receive signals from multiple transmitters, the method comprising: providing a plurality of received signals to N channel circuits of the receiver; isolating a first frequency bandwidth carrying a signal originating from a first transmitter in the plurality of received signals using a first band pass (BP) filter in a first channel circuit of the N channel circuits; adjusting the first frequency bandwidth provided by the first BP filter with respect to a reference voltage in a first gain control (GC) feedback circuit; isolating a second frequency bandwidth carrying a signal originating from a second transmitter in the plurality of received signals in a second channel circuit of the N channel circuits; and adjusting the second frequency bandwidth provided by a second BP filter with respect to the reference voltage in a second GC feedback circuit; wherein an N-way splitter is coupled to the first BP filter and the second BP filter, the N-way splitter providing the plurality of received signals to both the first BP filter and the second BP filter; and wherein a multiplexer is connected to the first GC feedback circuit and the second GC feedback circuit, the multiplexer combining an output from the first GC feedback circuit and the second GC feedback circuit to provide an output signal.
