Abstract
The present invention is directed to a dynamic range enhancing system for increasing the dynamic range of a transmission link, characterized as either an analog or digital link. The system includes a pre-processing unit, provided at a first location, that receives, as input, a transmit signal, and a post-processing unit, provided at a second location, remote from the first location, that receives, as input, a signal transmitted over the transmission link. The pre-processing unit includes a first signal level adjusting device for adjusting a signal level of the transmit signal to be transmitted over the transmission link and a control signal maybe provided for controlling the post-processing unit, and the post-processing unit includes a second signal level adjusting device for adjusting a signal level of the adjusted transmit signal transmitted over said transmission link. The transmit signal and the control signal maybe combined and transmitted over the transmission link together so as to eliminate synchronization problems. In this arrangement the overall system gain remains substantially constant.
