| With the development of wireless communication technology, how to ensure and enhance the reliability and effectiveness of communication become the main direction of research. Recently, more and more researchers began to apply the idea of network coding to wireless communications relay cooperative scenario in order to achieve cooperative diversity and channel coding gain. The idea of network coding is originally proposed to improve the capacity of wired network, in wireless network, however, the main purpose of its application is to achieve effectiveness of relay node. Thus, in various cell relay service users based collaboration/metadata network structures, the application of network coding technology enables the additional resources of relay stations to be more effectively utilized.This thesis mainly based on the transmission scenarios of wireless multiple access relay network, studied the design of combined different channel coding technique and network coding technique. The main purpose of this thesis, is to seek and design new ways of bonding channel coding and network coding technique as well as its corresponding decoding algorithm under the premise of ensuring the reliability and the transmission efficiency of the system transmission, to improve the reliability and efficiency of the system.The innovation of this paper is the design and application of joint network coding technique under various scenarios for wireless network, including multiple access relay channel and multiple way relay channel. Specifically, it combined different channel coding technique and network coding technique, proposed joint network coding scheme to improve the transmission performance of wireless relay networks. Thus, the proposed joint network coding theory opens up a new research direction in the field of wireless communication. |
