Abstract :
A promising candidate for the growing bandwidth requirements of interactive multimedia services are hybrid fiber-coax CATV networks. They are however very susceptible to noise-funneling. We present a measurement method and statistical postprocessing for both ingress and impulse noise that is independent of the modulation and access technique used. The impact of ingress noise is evaluated for a TDMA/FDMA and CDMA access technique to illustrate this.
