Abstract:
Previous research has identified several exact methods for the
evaluation of the probability of detection for energy detectors
operating on Nakagami-m faded channels. However, these methods rely on
discrete summations of complicated functions, and so can take a
prohibitively long time to evaluate. In this paper, three approximation for the probability of detection in Nakagami-m faded channels, having
distinct regions of applicability, are derived. All have closed forms,
and enable the fast and accurate computation of key performance metrics.
