中文摘要：
为有效传输多用户多中继网络信息,在线性网络编码的基础上给出一种基于正交处理的网络编码方法（NCOP,network coding based on orthogonal process）,该编码方式结合正交低频子载波处理思想,将传输数据正交化,利用处理后数据正交性实时传输并解码需要用户数据,进一步降低系统中断概率,提高分集增益。理论分析了该编码方法的系统中断概率和平均误码率,分析和仿真结果表明在多用户协作网络的应用中,NCOP中断性能及误码性能均优于线性网络编码。
英文摘要：
Combining the orthogonal low-frequency subcarrier processing, a network coding scheme based on orthogonal process （NCOP） was proposed for effective transmission in multi-user multi-relay networks. It makes the data orthogonal before transmission, and decodes the data utilizing the characteristics of orthogonality, so that further reduces the system outage probability and develops the diversity order. The system outage performance and average bit error rate was ana- lyzed by theoretical analysis. Analysis and simulation results show that the system performance of the proposed NCOP outperforms linear network coding while applying in multi-user cooperative networks.
