Second Order Statistics of SIR based Macro Diversity System for V2I Communications overComposite Fading Channels

The paper analyses second order statistics of macro selection combining (SC) diversity system for radio-frequency (RF) vehicle-to-infrastructure (V2I) communications over interference limited fading channels. In particular, the macro diversity (mac-div) reception is proposed in order to diminish the impact of the composite fading(multipath and shadowing). Novel, second order statistical infinite series expressions with fast convergence,such as level crossing rate, lcrand average duration of fades, afdareobtained, analyzed and graphically presented for different RFV2I sets of parameters.
