IMPULSE NOISE MODELLING IN THE UPSTREAM PATH OF HFC/CATV NETWORKS

摘要

Candidate for the growing bandwidth requirements of many interactive services, Cable Antenna Tele Vision (CATV) networks are subject to number of disturbances. Impulse noise, expanding by the noise funnelling phenomenon in the upstream path, is one of the worst impairments. This paper describes a realistic model of impulse noise in the upstream path of CATV network. These results are obtained after preliminary field trial measurement.
