Abstract

The application of the saddle point method for the evaluation of the probability density function of the decision variable at the receiver of a pre-amplified OOK (on-off keying) system in the presence of intrachannel crosstalk is investigated. It is shown that this method describes very well the tail of the density for any number of crosstalk terms, but lacks sufficient accuracy to describe values near its center, especially for a small number of crosstalk terms.
