Abstract
A system and method for supplying power to a headset, and for transmitting multiple signals generated in the headset to a terminal using frequency division multiplexing. An audio signal and a carrier signal are generated in the terminal and summed together to form a composite uplink signal. The composite uplink signal is provided to a headset over a first physical channel. At the headset, the audio and carrier signals are separated, and the carrier signal is used to generate power in the headset. Signals generated by a plurality of acoustic sensors in the headset are combined using frequency division multiplexing to generate a composite downlink signal, which is transmitted to the terminal over a second physical channel. One or more carrier signals used to generate the composite downlink signal are provided by either a carrier source in the headset, or by recovering the carrier signal from the composite uplink signal.
