Statistical characteristics of signal in the presence of two fast Nakagami-m and one slow Gamma fading

Abstract - In this paper is described model of forming equivalent envelope of a signal at the entrance of the wireless digital telecommunication system when there are present simultaneously two fast Nakagami-m and one slow Gamma fading. For the described model probability density function (PDF) of random variable at the reception side has been determined. Dependence of the probability density function (PDF) of the parameters of fading (fading severity) and corresponding components power is analytically and graphically described. Influences of the fading parameters on statistical characteristics of the received signal and quality of the signal detection in the entire communication system has been graphically shown.
