Fairness-aware power allocation for asymmetric two-way AF relaying networks
Chonglin Zhang, Jianhua Ge, Jie Li, Yun Hu · Electronics Letters · 2012
The outage performance fairness on asymmetric two-way amplify-and-forward (AF) relaying networks is investigated. Power allocation is proposed to minimise maximum individual outage probability so as to maintain the balance between the two end nodes. It is shown that the outage performance fairness is finally achieved under various traffic requirements. Furthermore, the proposed power allocation can also obtain the system balance and improve the overall system outage performance compared with conventional uniform power allocation.
