将 NOMA 技术应用于下行认知中继协作网络,提出基于 AF 的认知多用户中继协作 NOMA 系统(CM-RC-NOMA),给出了不同认知中继协作方案下 PU 和 SU 中断性能,并推导了其闭合表达式;同时将 AF中继协作方式与DF中继协作方式进行了对比。仿真结果表明,当SU到PU信道链路条件不差于BS到PU信道链路条件时,AF方式相比DF方式可以使PU获得更低的中断概率;另一方面,所提最佳认知中继协作方案相比传统最佳认知中继协作方案可以获得更佳的PU中断性能。
The non-orthogonal multiple access (NOMA) technology was studied in a downlink cognitive relay cooperation network.A cognitive multiuser relay cooperation based NOMA scheme was proposed (CM-RC-NOMA)
in which
the outage performance of PU and SU were given under different cognitive relay cooperation schemes and the corresponding outage expressions were also derived.At the same time
the AF based relay cooperation method and the DF based relay cooperation method were compared.The simulation results show that the lower outage of PU can be achieved by AF method compared with DF method
when the channel condition of BS to PU is no more than that of SU to PU.It is also revealed that the optimal outage performance of PU can be achieved by the proposed best cognitive relay cooperation scheme in contrast to the traditional best cognitive relay cooperation scheme.
