MAXIMIZATION OF TRANSINFORMATION IN PHOTODETECTION.

Abstract

A photodetector is considered as a communication channel and a study made of the maximum information per degree of freedom I which can be transmitted through the channel. Application of the calculus of variations yields a necessary equation which the input probability must satisfy when I is a maximum. It is found that for large average signal energy this necessary equation is satisfied when the input signal energy has an exponential probability density. The dependence of I an average signal energy with an input probability of this maximizing form is calculated numerically. (Author)
