Patent ID: 7299076

Claim:
A communication system for a vehicle, the communication system comprising: a microphone array comprising a plurality of microphone elements mounted within the vehicle for receiving an acoustic signal and converting the acoustic signal to an electrical signal; an antenna that is mounted proximate to the microphone array, the antenna communicating a radio frequency signal to a wireless device; and a controller located remotely from the microphone and antenna and having a first input that is electrically coupled to at least one microphone element in the microphone array and a second input that is electrically coupled to the antenna, the controller processing the electrical signal and transmitting the processed electrical signal to the antenna, a single cable that couples the controller to both the microphone array and the antenna; a multiplexer that is coupled to the single cable, the multiplexer multiplexing at least two of a power signal, the electrical signal and the radio frequency signal for transmission over the single cable; and a de-multiplexer that is coupled to the single cable, the de-multiplexer de-multiplexing the at least two of the modulated power signal, the electrical signal and the radio frequency signal transmitted over the single cable.
