Abstract
A central digital signal radio processor (DRSP) is separated from all analog inputs and outputs by digital data links. Each end of a data link couples to an interface which has transmit and receive capability using cancellation techniques to allow full duplex transmission. An antenna module located at the antenna processes much of tuning functions in analog and then converts the signal to digital and sends it to the DRSP for further processing. Transmitted digital signal from the DRSP are converted to analog by the antenna module and sent to the antenna. Microphones, tape and CD players and other inputs are similarly linked to the DRSP. The DRSP digital audio output is sent to speaker modules which convert to analog signals for driving speakers.
