摘要
从云无线接入网络(Cloud Radio Access Network,C-RAN)与非正交多址接入(Non-Orthgonal Multiple Access,NOMA)技术的概念着手,建立C-RAN下的NOMA模型,完成C-RAN架构内运用NOMA技术传输的中断理论分析工作。基于拉普拉斯变换等推导出用户中断率对应的闭式表达式,通过仿真模拟证实了理论推导的精准度,阐明了NOMA技术用在C-RAN架构中的优越性,值得推广。
Starting with the concepts of Cloud Radio Access Network(C-RAN)and Non-Orthgonal Multiple Access(NOMA),the NOMA model under C-RAN is established,and the interruption theory analysis of transmission using NOMA technology in C-RAN architecture is completed.Based on Laplace transform,the closed-form expression corresponding to user outage rate is derived.The accuracy of theoretical derivation is confirmed by simulation,and the superiority of NOMA technology in C-RAN architecture is expounded,which is worth popularizing.
