摘要:

线性网络编码协作(LNCC)是一种将线性网络编码与协作通信相结合的技术,能够提高频带利用率,降低中断概率.该文从理论上分析了双时隙M(M≥2)用户LNCC的紧近似中断概率,并通过Monte Carlo仿真验证了理论分析的正确性.同时,通过分析渐近中断概率,该文给出了双时隙M用户LNCC的分集阶数.为了说明线性网络编码为协作通信带来的额外增益,该文将双时隙M用户LNCC与分集阶数相同的传统M用户放大-转发协作系统进行了性能比较.结果发现,给定相同的有效频谱效率,前者的中断概率要显著低于后者.

Abstract:

Linear network coded cooperation (LNCC) is a technology that integrates linear network coding into cooperative communication.It can improve the spectrum efficiency and decrease outage probability of data transmissions.In this paper, the outage probability of the two-slots LNCC with M(M≥2) users is theoretically analyzed, tight approximated outage.Monte Carlo simulations are conducted to verify the theoretical analyses.Moreover, the asymptotic outage probability and the diversity order of two-slots M-users LNCC are also studied.In order to demonstrate the benefits introduced by linear network coding to cooperative communication, the performance comparison between the two-slots M-users LNCC and the traditional M-users Decode-and-Forward cooperation with the same diversity order is carried out.The results show that given the same effective spectrum efficiency, the outage probability of two-slots M-users LNCC is greatly lower than that of the latter.

Key words: cooperative communications, linear network coding, outage probability, multiuser
