Lubomir Kostal
We derive an approximate expression for mutual information in a broad class of discrete-time stationary channels with continuous input, under the constraint of vanishing input ampl…

Information transfer with small-amplitude signals
Lubomir Kostal, Petr Lansky
We study the optimality conditions of information transfer in systems with memory in the low signal-to-noise ratio regime of vanishing input amplitude. We find that the optimal mut…
