Abstract :
We examine the effect of a randomly time-varying channel on mutual information between the receiver and sender when the channel is mth 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
