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 (66) and a carrier signal (68) are generated in the terminal and summed together to form a composite uplink signal (70). The composite uplink signal (70) is provided to a headset (14) over a first physical channel (28). At the headset (14), the audio and carrier signals are separated, and the carrier signal (68) is used to generate power in the headset. Signals generated by a plurality of acoustic sensors (60, 62) in the headset are combined using frequency division multiplexing to generate a composite downlink signal (76), which is transmitted to the terminal over a second physical channel. |
