Abstract
Disclosed is a wireless remote controller using a time division protocol. A satellite radio equipped with the wireless remote controller is also disclosed which performs an audio processing operation for time division multiplexing (TDM) and orthogonal frequency division multiplexing (OFDM) signals respectively transmitted from satellites and a terrestrial repeater by demodulating and digitally processing the TDM and OFDM signals. The remote controller includes a transceiver for performing a bi-directional communication through a single channel in such a manner that transmission and reception sides are sync with each other in accordance with a time division duplexing scheme, the transceiver wirelessly transmitting a command from a user, and executing a response received thereto. A Bluetooth radio modem and a commercially available inexpensive protocol can be used, so that it is possible to inexpensively provide, to the driver, the same convenience and advantages as the conventional system. Also, the time division duplexing (TDD) wireless remote controller consumes reduced power. The wireless remote controller also allows the driver to manipulate the satellite radio for listening to …
