Error Exponents And Outage Probabilities For The Block-Fading Gaussian Channel

Abstract

A simple, generic model is examined for a slow-fading channel operated under both average input power and decoding delay constraints. In this model, applicable to digital cellular systems, the fade level is constant over intervals of K symbols. The exponential behavior of the average message error probability, as well as outage probabilities, are investigated. Numerical results for several types of diversity methods as well as for no diversity are presented and discussed.
