Traffic demand-aware topology control for enhanced energy-efficiency of cellular networks
收藏 引用
EURASIP JOURNAL ON WIRELESS COMMUNICATIONS AND NETWORKING 2016年 第1期000卷 1-17页
作者: Pollakis, Emmanuel Cavalcante, Renato L. G. Stanczak, Slawomir Heinrich Hertz Inst Nachrichtentech Berlin GmbH Fraunhofer Inst Telecommun Einsteinufer 37 D-10587 Berlin Germany Tech Univ Berlin Commun & Informat Theory Grp Einsteinufer 25 D-10587 Berlin Germany
The service provided by current mobile networks is not adapted to spatio-temporal fluctuations in traffic demand, but such fluctuations offer opportunities for energy savings. In particular, significant gains in energ... 详细信息

High-Dimensional Fused Lasso Regression Using majorization-minimization and Parallel Processing
收藏 引用
JOURNAL OF COMPUTATIONAL AND GRAPHICAL STATISTICS 2015年 第1期24卷 121-153页
作者: Yu, Donghyeon Won, Joong-Ho Lee, Taehoon Lim, Johan Yoon, Sungroh Keimyung Univ Dept Stat Taegu South Korea Seoul Natl Univ Dept Stat Seoul South Korea Seoul Natl Univ Dept Elect & Comp Engn Seoul South Korea
In this article, we propose a majorization-minimization (MM) algorithm for high-dimensional fused lasso regression (FLR) suitable for parallelization using graphics processing units (GPUs). The MM algorithm is stable ... 详细信息

Reweighted Nuclear Norm Approach for Interference Alignment
收藏 引用
IEEE TRANSACTIONS ON COMMUNICATIONS 2013年 第9期61卷 3754-3765页
作者: Du, Huiqin Ratnarajah, Tharmalingam Sellathurai, Mathini Papadias, Constantinos B. Univ Edinburgh Sch Engn Inst Digital Commun Edinburgh EH9 3JL Midlothian Scotland Heriot Watt Univ Sch Engn & Phys Sci Edinburgh EH14 4AS Midlothian Scotland Athens Informat Technol Athens 19002 Greece
Managing uncoordinated interference becomes a substantial problem for heterogeneous networks, since the unplanned interferences from the femtos cannot be coordinately aligned with that from the macro/pico base station... 详细信息

Fractional-order TV-L2 model for image denoising
收藏 引用
CENTRAL EUROPEAN JOURNAL OF PHYSICS 2013年 第10期11卷 1414-1422页
作者: Chen, Dali Sun, Shenshen Zhang, Congrong Chen, YangQuan Xue, Dingyu Northeastern Univ Shenyang 110819 Liaoning Peoples R China Univ Calif MESA Lab Merced CA 95343 USA
This paper proposes a new fractional order total variation (TV) denoising method, which provides a much more elegant and effective way of treating problems of the algorithm implementation, ill-posed inverse, regulariz... 详细信息
