Abstract

The authors present a generating function for runlength limited sequences intended for binary asymmetrical channels. The channel capacity for such channels is derived from this generating function. They present selected numerical values of channel capacity for these sequences. An expression for the power spectrum of binary maxentropic asymmetrical sequences is given and the influence of the asymmetry on the spectrum is investigated. Two new runlength limited modulation codes which are suitable for use on binary asymmetrical channels are investigated
