Orthogonal Physical Layer Network Coding Technology And DSP Emulation

The theories and technologies of cooperative communication and wireless physical layernetwork coding (physical-layer network coding, PNC) which are based on the relay are causingwidespread concern. Compared with the traditional one-way wireless relay strategy, the two-wayrelay makes wireless relay nodes on both sides of a two-way exchange of data packets, which helpto improve the throughput performance of the wireless network. Three of the wireless relay networknode according to the type of transmission slot, slot transmission scheme can be divided into four,three and two slots; According to the type of the signal processing, the physical layer networkcoding strategy used containing analog network coding and digital network coding. To avoid theneed for tight synchronization two-way communication of the transmitting node, the physical layernetwork coding nodes transmit three strategies can be employed a simple strategy of three slot, aphysical layer network coding strategy orthogonal.The main motivation and purpose of the topic is to review the progress of the new networkcoding, the relevant physical layer network coding, a detailed review of the literature. Focuses onthe physical layer network coding orthogonal and for the relevant module of "Wireless NetworkCoding Verification Platform"conducting detailed design,on this basis.Based on TI’s TMS320C6713DSP (digital signal processor) hardware platform, giving specific algorithm programming ideasand detailed description of the testing process,and realize the algorithm by using C language.Finally,the physical layer network coding transmission scheme was emulated on the DSP6713hardware platform.
