Energy-Efficient Hybrid Analog and Digital Precoding for MmWave MIMO Systems With Large Antenna Arrays
TLDR
This paper proposes a successive interference cancelation (SIC)-based hybrid precoding with near-optimal performance and low complexity, and proposes a low-complexity algorithm to realize SIC-based Hybrid precoding, which can avoid the need for the singular value decomposition and matrix inversion.

Large-scale antenna systems with hybrid analog and digital beamforming for millimeter wave 5G
TLDR
A reference signal design for the hybrid beamform structure is presented, which achieves better channel estimation performance than the method solely based on analog beamforming, and can be conveniently utilized to guide practical LSAS design for optimal energy/ spectrum efficiency trade-off.

Toward green and soft: a 5G perspective
TLDR
The perspective of the 5G technologies with two major themes: green and soft is presented, showing that by rethinking the Shannon theorem and traditional cell-centric design, network capacity can be significantly increased while network power consumption is decreased. Expand

TLDR
A systematic treatment of non-orthogonal multiple access, from its combination with MIMO technologies to cooperative NOMA, as well as the interplay between N OMA and cognitive radio is provided. Expand
Low-Complexity Soft-Output Signal Detection Based on Gauss–Seidel Method for Uplink Multiuser Large-Scale MIMO Systems
TLDR
This paper proposes to exploit the Gauss-Seidel method to iteratively realize the MMSE algorithm without the complicated matrix inversion, and proposes a diagonal-approximate initial solution to the GS method, which is much closer to the final solution than the traditional zero-vector initial solution.

Recent Progress on C-RAN Centralization and Cloudification
TLDR
This paper presents the latest progress on cloud RAN (C-RAN) in the areas of centralization and virtualization and demonstrates the viability of various front-haul solutions, including common public radio interface compression, single fiber bidirection and wavelength-division multiplexing. Expand
Multi-code CDMA wireless personal communications networks
TLDR
MC-CDMA is a wireless system whose rate and service are dynamically matched to users' needs and can evolve from commercial digital cellular systems and does not require significant modifications of the radio frequency (RF) circuitry. Expand
Machine learning inspired energy-efficient hybrid precoding for mmWave massive MIMO systems
TLDR
An adaptive CE (ACE)-based hybrid precoding scheme that aims to adaptively update the probability distributions of the elements in hybrid precoder by minimizing the CE, which can generate a solution close to the optimal one with a sufficiently high probability. Expand
