Analysis and Modeling of Intermodulation Distortion in Wide-Band Cable TV Channels

This correspondence deals with the development of a practical approach for the assessment of intermodulation distortion in modern cable television (CATV) systems operating over the 400 MHz range. In particular, Volterra series expansions are used in establishing appropriate high-frequency models for the description of such wide-band CATV channels. Furthermore, experimental measurements made on a typical system are utilized to illustrate the development of Volterra models which may be used subsequently in the prediction of intermodulation distortion in such systems.
