Power allocation and group assignment for reducing network coding noise in multi-unicast wireless systems

Mobini, Zahra; Sadeghi, Parastoo; Khabbazian, Majid; Zokaei, Saadan

Description

In this paper, we consider physical-layer network coding (PNC) in a multi-unicast wireless cooperative network with a single relay. We aim to deal with the NC noise, i.e., an additional noise term due to applying NC, with the objective of improving the network data rate. Our approaches are based on relay power-allocation and group-allocation techniques. To this end, we provide a mathematical framework for the achievable information rate of the system with the notion of power assignment at the...[Show more]
