WebAs a fading model we chose Rayleigh model (not Fast Rayleigh model). This choice enabled us to see the deterioration of the communication between fading and no fading environments. We chose one UDP connection and collected data to the figures: 1- Average UDP packet delay with and without fading. Webupper bound to the outage probability of Rayleigh and Rician block-fading channels is proposed in [9], [10]. In this paper, we propose a tight lower bound to the outage probability which can be efﬁciently evaluated for the general Nakagami-m block-fading channel [11]. We also show that the optimal rate-
