下行链路OFDM-NOMA系统的子载波和功率分配方案

以最大化缓存收益为目标，针对部署缓存的 NOMA 异构网络下的基站用户匹配及功率分配问题，结合消息传递及 DC 规划提出了 NOMA 联合优化算法。首先将约束条件合并到目标函数中，通过计算新的优化问题中函数节点与变量节点间消息传递的边缘得到用户协同结果；然后将原优化问题变形为2个凸函数差的形式，通过DC规划对功率资源进行分配；最后迭代计算得到最终的用户协同及功率分配结果。仿真结果证明所提算法有效地提升了网络性能。

面向5G的非正交多址接入技术-NOMA-浅析.zip

NOMA(非正交多址接入): （摘自《面向5G的非正交多址接入技术（NOMA）浅析》.张长青） 1.1基本原理：        在正交多址技术（OMA）中，只能为一个用户分配单一的无线资源，例如按频率分割或按时间分割，而NOMA方式可将一个资源分配给多个用户。NOMA技术的基础仍是成熟的OFMA技术，NOMA在同一个子载波，同一个OFDM符号对应的同一个资源单元上，根据不同的信号功率为多个用户使用，可达到多址接入的目的。        NOMA在发送端根据对信道传输质量的评估来分配用户发射功率的非正交发送，主动引入干扰信息。对信噪比高的信道分配较小的功率，对信噪比低的信道分配较大的功率。在接

Non-orthogonal multiple access (NOMA), an emerging technology to improve system capacity and spectrum efficiency, has attracted significant attention. In this study, the authors propose a NOMA-based downlink cooperative cellular system, where the base station communicates with two paired mobile users simultaneously through the help of a half-duplex amplify-and-forward relay. The outage performance of the system is investigated and closed-form expressions for their respective exact and asymptotic outage scheme are derived. Furthermore, they study the ergodic sum rate of the two paired users and the upper bound of the ergodic sum rate is obtained. By comparing the NOMA with conventional multiple access (MA) via numerical simulations, they have shown that NOMA can obtain the same diversity order with conventional MA, and achieve nearly the same sum rate with conventional MA. Furthermore, NOMA can offer better spectral efficiency and user fairness since more users are served at the same time, frequency, and spreading code.
