In order to enhance the ability of harmonic suppression for multi-pulse converters (MPCs). This paper proposes a novel pulse multiplication method at DC side of MPCs. The presented rectifier consists of a three-phase bridge parallel structure 12-pulse rectifier and a novel double winding tapped inter-phase converter (TIPC). The functions and characteristics of delta-connected autotransformer and ZSBT...
The tremendous popularity of smart phones and electronic tablets has spurred the explosive growth of high-rate multimedia wireless services. To alleviate the huge infrastructure investment in the exponential growth of mobile traffic and improve local service flexibility, device-to-device (D2D) communications have been considered for the next generation mobile telecommunications. This has triggered...
Based on one or several views, view synthesis creates other views for the purpose of view prediction (for compression) or view rendering (for multiview-display). Luminance adjustment and hole filling are two key issues in view synthesis. In this paper, two views are used to produce an arbitrary virtual synthesized view. One view is merged into another view using a local luminance adaptive adjustment...
Transmit beamforming can be performed to achieve capacity gains by spatially multiplexing multiple users and reduce outages by spatial interference mitigation. In this paper, we investigate the multiuser multiple input single output (MU-MISO) transmission in a two-tier femtocell network where base stations in each tier follow an independent Poisson point process (PPP), and provide insights into the...
For personal identification, iris recognition is an excellent biometrics method with high accuracy, but it is very difficult to acquire good-quality iris images in real time. In order to make iris recognition more convenient to use, we design an iris recognition system at a distance about 30 centimeters. There are five key modules to design such a system, including image focusing, iris images acquisition,...
As the mobile Internet gradually penetrates into the daily life, it is becoming the most important way people acquire information. Statistical characteristics of users' data access behavior can be used as the foundation for optimization of network deployment, or even trigger new business models. In this paper, distribution patterns of the subscriber's data access behavior have been discussed both...
