Abstract

In this letter, we consider multi-pair two-way relay networks where multiple user pairs simultaneously exchange information via a common multi-antenna relay station. We develop a relaying protocol based on analogue network coding to avoid inter-pair interference in such networks. The user pair selection and power allocation for active user pairs are developed and integrated in the design to enhance the system sum rate. Numerical results show that our proposed design can significantly increase the sum rate compared with the existing scheme.
