Hybrid beamforming for large-scale MIMO systems using uplink-downlink duality

Ganapati Hegde, Yong Cheng, Marius Pesavento

ICASSP 2017accepted

We consider the problem of designing hybrid analog-digital beamformers in a downlink multi-user large-scale MIMO system. The objective is to minimize the total transmit power, while fulfilling SINR targets of all users. A dual virtual uplink problem is formulated for the original downlink problem ba…

Optimal resource block allocation and muting in heterogeneous networks

Ganapati Hegde, Oscar Dario Ramos-Cantor, Yong Cheng, Marius Pesavento

ICASSP 2016accepted

In this paper, we investigate user association and resource block (RB) allocation in downlink heterogeneous cellular networks. Our goal is to jointly optimize user association and RB allocation to maximize network throughput while taking into account fairness among users. To effectively control inte…
