A Novel Hybrid Beamforming Algorithm with Unified Analog Beamforming by Subspace Construction Based on Partial CSI for Massive MIMO-OFDM Systems
Dengkui Zhu, Boyu Li, Ping Liang
Hybrid beamforming (HB) has been widely studied for reducing the number of costly radio frequency (RF) chains in massive multiple-input multiple-output (MIMO) systems. However, pre…
On the Matrix Inversion Approximation Based on Neumann Series in Massive MIMO Systems
Dengkui Zhu, Boyu Li, Ping Liang
Zero-Forcing (ZF) has been considered as one of the potential practical precoding and detection method for massive MIMO systems. One of the most important advantages of massive MIM…
Power Allocation for Precoding in Large-Scale MIMO Systems with Per-Antenna Constraint
Dengkui Zhu, Boyu Li, Ping Liang
Large-scale MIMO systems have been considered as one of the possible candidates for the next-generation wireless communication technique, due to their potential to provide signific…
Normalized Volume of Hyperball in Complex Grassmann Manifold and Its Application in Large-Scale MU-MIMO Communication Systems
Dengkui Zhu, Boyu Li, Ping Liang
This paper provides a solution to a critical issue in large-scale Multi-User Multiple-Input Multiple-Output (MU-MIMO) communication systems: how to estimate the Signal-to-Interfere…
Small Cell In-Band Wireless Backhaul in Massive MIMO Systems: A Cooperation of Next-Generation Techniques
Boyu Li, Dengkui Zhu, Ping Liang
Massive multiple-inputmultiple-output (MIMO) systems, dense small-cells (SCs), and full duplex are three candidate techniques for next-generation communication systems. The coopera…
