This paper investigates the affects of upstream channel distortion in HFC networks for serving areas of different size, rf channel bandwidth, modulation scheme, and operating frequency. Experimental characterization of the reverse upstream channel as well as digital transmission performance simulation for a variety of cases are presented. Upstream channel availability results based on a minimum BER performance of 10-8 with and without the use of equalization are presented as well.
