Abstract:
1. A software defined radio communications system comprising: a first programmable circuit programmed to convert a first digital audio signal into a first analog transmit signal and convert a first analog receive signal into a first digital receive signal, the first analog transmit signal and the first analog receive signal conforming to a first set of radio signal parameters characterizing a first radio communications channel; at least one second programmable circuit coupled to the first programmable circuit, the at least one second programmable circuit being programmed to convert at least one second digital transmit signal into at least one second analog transmit signal and convert at least one second analog receive signal into at least one second digital receive signal, the at least one second analog transmit signal and the at least one second analog receive signal conforming to at least one second set of radio signal parameters characterizing at least one second radio communications channel, the first programmable circuit and the at least one second programmable circuit being identical; a digital highway coupling the first programmable circuit and the at least one second programmable circuit, the first digital receive signal being provided to any one of the at least one second programmable circuits and the at least one second digital receive signal being provided to the first programmable circuit; and a control system configured to program the first programmable circuit to conform to the first set of radio signal parameters, to program the at least one second programmable circuit to conform to the at least one second set of radio signal parameters, and to program the first programmable circuit and the at least one second programmable circuit to conform to a predetermined radio communications channel patching arrangement.
