讲座摘要:
作为一项潜在的5G关键技术,非正交多址接入(NOMA)技术已受到来自学术界和工业界的广泛关注。在NOMA系统中,多个用户同时使用相同的载波频率,在接收端采用串行干扰消除(SIC)方法对数据进行解调。尽管串行干扰消除的理念提出已久,但直到近年才被视为无线网络中的实用解决方案。为正常进行串行干扰消除,接收端的信号与干扰加噪声比(SINR)需要足够高才能进行数据成功解调以及后续的干扰消除。为满足该要求,发射端功率控制成为不可或缺的部分。该讲座重点讲解NOMA系统中蜂窝小区间的干扰管理。讲座将回顾基于非负矩阵的佩龙-弗洛比尼斯定理(Perron-Frobenius theory)的经典功率控制算法,并讲解如何将其应用于多蜂窝NOMA系统。考虑到5G系统中实际应用,本讲座还将讨论如何将其设计为分布式的功率控制算法。
