Random walks on networks: cumulative distribution of cover time
Nikola Zlatanov, Ljupco Kocarev
We derive an exact closed-form analytical expression for the distribution of the cover time for a random walk over an arbitrary graph. In special case, we derive simplified exact e…
Level Crossing Rate and Average Fade Duration of the Multihop Rayleigh Fading Channel
Zoran Hadzi-Velkov, Nikola Zlatanov, George K. Karagiannidis
We present a novel analytical framework for the evaluation of important second order statistical parameters, as the level crossing rate (LCR) and the average fade duration (AFD) of…
On the Second Order Statistics of the Multihop Rayleigh Fading Channel
Zoran Hadzi-Velkov, Nikola Zlatanov, George K. Karagiannidis
Second order statistics provides a dynamic representation of a fading channel and plays an important role in the evaluation and design of the wireless communication systems. In thi…
Level Crossing Rate and Average Fade Duration of the Double Nakagami-m Random Process and Application in MIMO Keyhole Fading Channels
Nikola Zlatanov, Zoran Hadzi-Velkov, George K. Karagiannidis
We present novel exact expressions and accurate closed-form approximations for the level crossing rate (LCR) and the average fade duration (AFD) of the double Nakagami-m random pro…
An Accurate Approximation to the Distribution of the Sum of Equally Correlated Nakagami-m Envelopes and its Application in Equal Gain Diversity Receivers
Zoran Hadzi-Velkov, Nikola Zlatanov, George K. Karagiannidis
We present a novel and accurate approximation for the distribution of the sum of equally correlated Nakagami-m variates. Ascertaining on this result we study the performance of Equ…
