Full Duplex of V2V Cooperative Relaying over Cascaded Nakagami-m Fading Channels

摘要

In this paper, we consider full duplex amplify and forward (AF) relay networks in vehicle-to-vehicle (V2V) applications. In this context, taking into account the self-interference (SI) at the relay and assuming independent and not necessarily identically distributed (i.n.i.d) generalized L-Nakagami-m fading channels, we derive novel expressions for the probability density function (PDF) and cumulative distribution function (CDF) of the signal-to-interference-plus-noise ratio at the relay. Capitalizing on this, a lower bound to the end-to-end outage probability is derived. Monte-Carlo simulation results are presented to corroborate the derived analytical results. Our results show that the channel cascading significantly impacts the end-to-end outage probability of full duplex (FD) relaying V2V systems, where the cascading of the source-relay link is shown to be more significant than that of the relay-destination link.
