Analytical Level Crossing Rate and Average Outage Duration for MRC Combiner in Log Normal Shadowed Channels
نویسندگان
چکیده
We provide an analytical approach for the evaluation of important second order statistical parameters, as level crossing rate (LCR) and average outage duration (AOD) of MRC combiner in Log-Normal shadowed channels. New expressions have been derived for LCR and AOD in closed form. The results are valid for an arbitrary number of independent identically distributed diversity branches in the presence of Log -Normal shadowed. The output of MRC combiner has been estimated using Fenton-Wilkinson method. LCR and AOD have been plotted and also tabulated for different number of diversity branches. The results that we provide in this paper are an important tool for measuring the performance of communication links in a log-normal shadowing. Index Terms – Level Crossing Rate (LCR), Average Outage Duration (AOD), Maximal Ratio Combining (MRC), LogNormal shadowed (LN), Signal to Noise Ratio (SNR), Independent Identically Distributed (IID)
