Software-Defined Hyper-Cellular Architecture for Green and Elastic Wireless Access
Sheng Zhou, Tao Zhao, Zhisheng Niu +1
To meet the surging demand of increasing mobile Internet traffic from diverse applications while maintaining moderate energy cost, the radio access network (RAN) of cellular system…
Joint Deployment of Small Cells and Wireless Backhaul Links in Next-Generation Networks
Xiangxiang Xu, Walid Saad, Xiujun Zhang +2
In this paper, a novel approach for optimizing the joint deployment of small cell base stations and wireless backhaul links is proposed. This joint deployment scenario is cast as a…
A Multi-cell MMSE Precoder for Massive MIMO Systems and New Large System Analysis
Xueru Li, Emil Björnson, Erik G. Larsson +2
In this paper, a new multi-cell MMSE precoder is proposed for massive MIMO systems. We consider a multi-cell network where each cell has users and orthogonal pilot sequence…
A Multi-cell MMSE Detector for Massive MIMO Systems and New Large System Analysis
Xueru Li, Emil Björnson, Erik G. Larsson +2
In this paper, a new multi-cell MMSE detector is proposed for massive MIMO systems. Let and denote the number of users in each cell and the number of available pilot sequen…
Massive MIMO with Multi-cell MMSE Processing: Exploiting All Pilots for Interference Suppression
Xueru Li, Emil Björnson, Erik G. Larsson +2
In this paper, a new state-of-the-art multi-cell MMSE scheme is proposed for massive MIMO networks, which includes an uplink MMSE detector and a downlink MMSE precoder. The main no…
