为了满足未来5G在频谱效率和连接数等方面的需求,非正交多址接入技术日益受到产业界的重视。从多用户信息论的角度,首先,探讨非正交多址接入与正交多址的理论性能比较及其逼近多用户信道容量界的有效途径;其次,对功率域、星座域、码域3种非正交多址方案的设计原理、信号处理和性能增益进行了深入分析;最后,从网络运营的角度剖析了非正交多址接入技术的应用场景、对系统设计带来的影响和网络后向兼容性等问题。
To meet the 5G requirements on spectral efficiency and number of connections,non-orthogonal multiple access(NMA)technology is becoming an important candidate technology.It was shed light on how NMA can be used to further improve spectral efficiency over OMA,in order to achieve the multiple user channel capacity.Detailed analysis were given on the design principle,signal processing and resultant performance gain of three typical NMA schemes including power-domain,constellation-domain and code-domain NMA.Furthermore,network operating aspects for NMA like deployment scenarios,system design impact as well as network backward compatibility were presented.
