The effect of an randomly time-varying channel on mutual information
Muriel Médard, Robert G. Gallager · 2002
We examine the effect of a randomly time-varying channel on mutual information between the receiver and sender when the channel is m/sup th/ order Markov. Such channels often occur in mobile communications and can affect the achievable rate. If the channel is perfectly known, then the mutual information between a receiver and an arbitrary number of senders may be found, even if the channel is time-varying.
