The Industrial Internet of Things (IIoT) has been viewed as a typical application for the fifth generation (5G) mobile networks. This article investigates energy efficiency (EE) optimization problem Device-to-Device (D2D) communications underlaying unmanned aerial vehicles (UAVs)-assisted IIoT networks with simultaneous wireless information and power transfer (SWIPT). We aim to maximize EE system while satisfying constraints transmission rate budget. However, designed is nonconvex involving...
In this paper, we propose an integrated micro-optical light guide plate (MOLGP), of which the top surface is designed as aspheric semi-cylindrical micro-concentrator structure (ASCMCS) arrays and bottom fused with micro-prism coated a high-reflective film. And also present optimized structural parameters distribution pattern MOLGP. By simulation professional optical software Lighttools, it's verified that MOLGP proposed can achieve functions five complex-structure films in current typical...
The luminance uniformity of the backlight module (BLM) importantly depends on microstructure distribution bottom surface light guide plate (LGP). Based small-size integrated LGP (ILGP) proposed, we put forward a expression micro-prisms ILGP, and present relational expressions between coefficients analytical structural parameters such as length L, width ILGP W, thickness H, space emitting diodes (LEDs) d. Then, research results above are applied to design ILGPs. Not only can micro-structure...
Based on the backlight module (BLM) with an integrated micro-optical light guide plate (MOLGP) that we proposed [Opt. Express21, 20159 (2013)], optical model maps relationship between distribution of microprisms bottom surface MOLGP and luminance output is established by a backpropagation neural network in this paper. Then optimized for high uniformity obtained genetic algorithm. Finally, BLM set up software, simulation results show reaches 93%.
This paper investigates the energy efficiency (EE) optimization problem for device-to-device (D2D) communications underlaying non-orthogonal multiple access (NOMA) unmanned aerial vehicles (UAVs)-assisted networks with simultaneous wireless information and power transfer (SWIPT). Our aim is to maximize of system while satisfying constraints transmission rate budget. However, considered EE non-convex involving joint UAV's location, beam pattern, control time scheduling, which difficult solve...
