Abstract

In this paper, we investigate transmit power optimization in a network based on asymmetric two-way semi-blind amplify-and-forward (AF) relaying and opportunistic relay selection. After processing the asymptotic outage probabilities based on partial channel state information (CSI) at relays, we provide the optimization of power allocation which aims to minimize the total transmit power under outage probabilities constraints. The proposed results are validated by simulations and compared to well known reference which is asymmetric two-way CSI-assisted AF relaying system.
