Implicit channel estimation for ML sequence detection over finite-state Markov communication channels
Krusevac, Zarko; Kennedy, Rodney; Rapajic, Predrag
This paper shows the existence of the optimal training, in terms of achievable mutual information rate, for an output feedback implicit estimator for finite-state Markov communication channels. Implicit (blind) estimation is based on a measure of how modified is the input distribution when filtered by the channel transfer function and it is shown that there is no modification of an input distribution with maximum entropy rate. Input signal entropy rate reduction enables implicit (blind) channel...[Show more]
