A novel and collaborative network channel coded mobile communication architecture

This paper presents a novel algebraic framework of collaborative network channel coding scheme in a network with multiple-access relay channel. The proposed scheme helps reduce the computational complexity while enhancing energy efficiency of the wireless network. The devised scheme is intended for practical scenarios where channels exhibit various fading conditions over all the wireless links. We use network coding at the relay to give diversity boost at the receiver with lesser number of transmitted signals and lesser energy consumption. The setup demonstrates improved performance that is instrumental for the effective use of joint network channel coding (JNCC) for practical wireless networks. We further present a performance metric Energy Efficiency for the better performance evaluation.
