Multi-hop wireless transmission with half duplex and imperfect full duplex relays

A multi-hop wireless transmission system employing both half duplex and imperfect full duplex relays is proposed. In this scheme, which uses Ksub-channels for transmission and reception over Rayleigh fading channels, we aim to mitigate the most dominant source of interference in each node by allocating different sub-channels to various groups of nodes. The outage probability of the proposed scheme under decode and forward relaying is analyzed and a closed form expression is obtained and validated by simulation. The proposed multi-hop transmission scheme based on full and half duplex relays, although less complex, still improves the outage probability of the network in comparison to complete full duplex multi-hop relaying.
