Generalised Channel State Information Outdatedness Modelling Using MRC

This paper offers unified modelling for opportunistic-relay outdatedness using the joint distribution of bivariate exponential-correlated generalised-Rician fading. Line-of-sight power and larger-than-two degrees of freedom under independently-and-identically-distributed Rayleigh fading environments employing maximal ratio combining (MRC) are considered. Unavoidable infinite summations are employed, which are shown to fast-converge for a finite number of terms. Ergodic channel capacity is employed for performance assessment. Thorough comparisons between performance of selection combining and MRC are also given. Monte Carlo simulation is employed to validate this work.
