Interference Management in Massive MIMO HetNets: A Nested Array Approach
Mingjie Feng, Shiwen Mao
The nested array, which is implemented by nonuniform antenna placement, is an effective approach to achieve O(N^2) degrees of freedom (DoF) with an antenna array of N antennas. Suc…
CSI-based Fingerprinting for Indoor Localization: A Deep Learning Approach
Xuyu Wang, Lingjun Gao, Shiwen Mao +1
With the fast growing demand of location-based services in indoor environments, indoor positioning based on fingerprinting has attracted a lot of interest due to its high accuracy.…
BOOST: Base station on-off switching strategy for energy efficient massive MIMO HetNets
Mingjie Feng, Shiwen Mao, Tao Jiang
In this paper, we investigate the problem of optimal base station (BS) ON-OFF switching and user association in a heterogeneous network (HetNet) with massive MIMO, with the objecti…
Harvest the potential of massive MIMO with multi-layer techniques
Mingjie Feng, Shiwen Mao
Massive MIMO is envisioned as a promising technology for 5G wireless networks due to its high potential to improve both spectral and energy efficiency. Although the massive MIMO sy…
