System Performances in the Presence of One Fast Weibull and One Slow Gamma fading

This paper decribes the model of forming equivalent envelope of a signal at the entrance of the wireless digital telecommunication system when there are present simultaneously one fast Weibull and one slow Gamma fading. Probability density function (PDF) of random variable at the reception side has been determined for the described model. Dependence of the probability density function (PDF) of the parameters of fading (fading severity) and corresponding components power is analytically and graphically described. The influence of fading parameters on statistical characteristics of the received signal and quality of the signal detection in the entire communication system has been graphically shown.
