RF communication systems are often applied in agricultural communication systems and other applications in smart agriculture. Performance of RF communication system consisting of a macrodiversity system with 2 SC (Selection Combiner) microdiversity receivers is analyzed in this paper. Processing done on one diversity branch made SC diversity receiver suitable for practical realization. The SC receiver extracts the branch with the highest signal-to-noise ratio. When the noise power in all branches is the same, branch with the strongest signal in the SC receiver is selected. Two input SC receiver with k-μ fast fading and slow gamma fading is considered. Analytical expression of LCR (Level Crossing Rate) for the given system is calculated. Numerical and graphical results based on the given analytical expression were obtained. Results show LCR behavior and received signal performance of the macrodiversity system depending on several system parameters: Ricean k factor, the depth of channel shading c and the number of clusters μ.
