SYSTEM AND METHOD FOR ENHANCING THE PERFORMANCE OF WIDEBAND DIGITAL RF TRANSPORT SYSTEMS

摘要

The host unit (101), disclosed herein, comprises: a plurality of inputs, each input configured to receive a wideband RF signal; a plurality of analog to digital converter circuits (102), each coupled to a selected one of the plurality of inputs, wherein each analog to digital converter circuit (102) is configured to generate a sample stream, wherein each analog to digital converter circuit (102) is configured to operate at a selected sample rate related to a signal bandwidth of its associated wideband RF signal; and a multiplexer circuit configured to multiplex together the plurality of sample streams into one serial bit stream at a fixed bit rate. The host unit (101), as comprised in the system (100), is coupled to a remote unit (103) via a transmission medium (111), the remote unit (103) comprising: a demultiplexer circuit configured to demultiplex the serial bit stream into a plurality of sample streams; a plurality of digital to analog converter circuits (118), each digital to analog converter circuit (118) configured to generating a wideband RF signal from one of the plurality of sample streams, wherein each digital to analog converter circuit (118) is configured to operate at an output sample rate related to a signal bandwidth of its associated wideband RF signal; and a plurality of outputs, each output coupled to a selected one of the plurality of the plurality of digital to analog converter circuits, wherein each output is configured to output a wideband RF signal.
