Extending the ITU-R P.530 Deep-Fading Outage Probability Results to SIMO-MRC and MIMO-MRC Line-of-Sight Systems

In this letter, we propose a method extending the deep-fading outage probability results of the ITU-R P.530 to the single-input multiple-output (SIMO)-maximum ratio-combining (MRC) and MIMO-MRC cases. By deducing the similarity between the analytical expressions of correlated Rayleigh fading and the ITU-R P.530 formulations, we utilize the ITU-R P.530 correlation information in order to estimate the outage probability of SIMO-MRC and MIMO-MRC systems. Finally, we demonstrate the significant reduction (of several orders of magnitude) in the worst month deep-fading outage probability that can be achieved using SIMO-MRC and MIMO-MRC for different fading depths and antenna spacings.
