In this paper we will observe wireless propagation in non-homogenous environment under non-deterministic line-of-sight (LOS) conditions, when the random nature of dominant/scattering components ratio has been considered and modeled as Gamma distribution. First closed-form expressions have been derived for the probability density function (PDF) and cumulative distribution function (CDF) of the observed fading process. Further performance analysis of wireless transmission over given conditions has been carried out through the standard criterions, such as outage probability (OP) and average bit error probability (ABER). Numerically obtained results have been graphically presented and discussed in the function of transmission parameters.
