This paper investigates a layered power allocation (PA) non-orthogonal multiple access (NOMA) scheme for device-to-devic......

We propose a thoroughly optimal signal design strategy to achieve the Pareto boundary (boundary of the achievable rate r......

在多小区大规模多输入多输出（MIMO）系统中,针对各小区复用相同导频序列进行信道估计存在有导频污染问题,提出了一种大规模MIMO系统中......

针对经典CS信道估计算法在低信噪比情况下对信道状态信息估计不够精准的问题,结合基于透镜的毫米波大规模MIMO可以显著减少所需RF......

在大规模MIMO系统下行链路中,MMSE和SVD波束成形算法的和速率性能要优于ZFBF和MRT波束成形,其代价在于MMSE和SVD的计算复杂度远大......
