Abstract
A new class of channel models with memory is presented in order to study various kinds of interference phenomena. It is shown, among other things, that when all other parameters are held fixed, channel capacity
is an {em increasing} function of the memory length, while the cutoff rate
generally is a {em decreasing} function. Calculations with various explicit coding schemes indicate that
is better than
as a performance measure for these channel models. As a partial resolution of this
versus
paradox, the conjecture is offered that
is more properly a measure of coding delay rather than of coding complexity.
