A DIAGRAMMATIC APPROACH TO STUDY THE INFORMATION TRANSFER IN WEAKLY NONLINEAR CHANNELS
A DIAGRAMMATIC APPROACH TO STUDY THE INFORMATION TRANSFER IN WEAKLY NONLINEAR CHANNELS
In a recent work we have introduced a novel approach to study the effect of weak nonlinearity in the transfer function on the information transmitted by an analogue channel, by means of a perturbative diagrammatic expansion. We extend here the analysis to all orders in perturbation theory, which allows us …
