International Conference on Artificial Reality and Telexistence (ICAT)

What we perceive with our senses becomes the basic real time information that directs and helps with the tasks we do. Our perception may represent the real world environment or what is perceived is a view of the real world modified with simulated elements of the environment. Augmented reality (AR) represents a system where a view of a live real physical environment is supplemented by computer-generated elements such as sound, video, graphic or location data. Development of AR systems has been facilitated by the advancement in both hardware and software technologies, making it easier to implement all functionalities in real time. Such real time enhancements have been helped by new techniques in such areas as computer vision, object recognition, and registration methodologies which enable user to interact with and manipulate the real world environment effectively. AR advanced computer graphics is integrated to real world data and viewed by the user using see-through head mounted display (HMD). This immersion of the integrated real and simulated world provides a unique perception to users. What he sees, feels, hears, and smells is indistinguishable between what is real and what is computer-generated. Technology has propelled AR systems from experimental laboratories to the marketplace demonstrating great promise in the fields of arts, architecture, archaeology, commerce, construction, education, entertainment, gaming, system maintenance, medical and military applications.

Among all SLAs(Service Level Agreements) about network resources in the cloud, a critical problem would be achieving bandwidth guarantee under all communication environment (e.g., when misbehaved VMs exist) while keeping acceptable bandwidth utility and system scalability. In this paper, we present an architecture of dynamic bandwidth allocation and guarantee on resource fairness, to provide network performance isolation and protocol independent bandwidth guarantees. In this paper, we first discuss the business model of bandwidth guarantee for Infrastructure-as-a-Service (IaaS) cloud, and a bandwidth allocation algorithm based on redefined fairness model is proposed and realized under the novel architecture, and finally experiment shows satisfying results under various communication scenarios. © 2013 IEEE.

Frontiers of Optoelectronics 2013年第1期6卷 46-56页

作者： Zhengxuan LI Lilin YI Weisheng HU The State Key Lab of Advanced Optical Communication Systems and Networks Department of Electronic Engineering Shanghai Jiao Tong University Shanghai 200240 China

In this paper, key technologies, system proposals and future directions of next generation passive optical networks stage 2 (NG-PON2) are reviewed. We first discuss the potential solutions for NG-PON2 standardization. Then we focus on time and wavelength division multiplexed PON (TWDM-PON), which is the primary solution selected by Full Service Access Network (FSAN). The key technologies in TWDM-PON configuration are analyzed, including how to improve the bandwidth capacity and power budget of the system, and choose upstream tunable transceiver, etc. Several system proposals are illustrated as candidates for NG-PON2 configuration.

Pipeline structure Schnorr-Euchner Sphere Decoding Algorithm

引用

communications and Network 2013年第3期5卷 108-112页

作者： Xinyu Mao Jianjun Wu Haige Xiang State Key Laboratory of Advanced Optical Communication Systems & Networks School of Electronics Engineering and Computer Science Peking University Beijing China

We propose a pipeline structure for Schnorr-Euchner sphere decoding algorithm in this article. It divides the search tree of the original algorithm into blocks and executes the search from block to block. When one block search of a signal is over, the part in the pipeline structure that processes this block search can load another signal and search. Several signals can be processed at the same time in one pipeline. Blocks are arranged to lower the whole complexity in the way that the previously search blocks are the blocks those have more probability to generate the final solution. Simulation experiment results show the average process delay can drop to the range from 48.77% to 60.18% in a 4-by-4 antenna system with 16QAM modulation, or from 30.31% to 61.59% in a 4-by-4 antenna system with 64QAM modulation.
