Study on the Statistical Performance of Relay Cooperation Over Non-Isotropic Mobile-to-Mobile Nakagami-m Fading Channels

Abstract:

This work focuses on the investigation of the second-order statistical descriptions for full mobile wireless networks over non-isotropic Nakagami-m fading environment. The system consists of a source, a relay, and K destination users, all of which are mobile. For the full mobile system model, we first extend the Akki and Habers mobile-to-mobile (M2M) model to non-isotropic scattering fading channels by adopting the von Mises PDF for both the angle of arrival (AnOA) and the angle of departure (AnOD). With appropriate mathematical proof, we obtain the approximate solution to the correlation function of M2M Nakagami-m fading channel envelop, and the variance of the first derivative. Secondly, using the obtained correlation, we study the average outage rate (AOR) and the average outage duration (AOD) of the multi-user single relay cooperation system in detail, and obtain the closed-form analytical expressions to AOR and AOD.
