Mobile Edge Computing(MEC)-based computation offloading is a promising application paradigm for serving large numbers of users with various delay and energy *** this paper,we propose a flexible MECbased requirement-adaptive partial offloading model to accommodate each user's specific preference regarding delay and energy *** address the dimensional differences between time and energy,we introduce two normalized parameters and then derive the computational overhead of processing *** from existing works,this paper considers practical variations in the user request patterns,and exploits a flexible partial offloading mode to minimize computation overheads subject to tolerable delay,task workload and power *** the resulting problem is non-convex,we decouple it into two convex subproblems and present an iterative algorithm to obtain a feasible offloading *** experiments show that our proposed scheme achieves a significant improvement in computation overheads compared with existing schemes.

High-Performance Beamformer and Low-Complexity Detector for DF-Based Full-Duplex MIMO Relaying Networks

China Communications 2017年第2期14卷 173-182页

作者： Feng Shu Ye Zhou Riqing Chen Jin Wang Jun Li branka vucetic College of Computer and Information Sciences Fujian Agriculture and Forestry University Fuzhou 350002 China School of Mobile Network Nanjing Technology University Pujiang Institute Nanjing 21134 China School of Electronic and Optical Engineering Nanjing University of Science and Technology Nanjing 210094 China National Mobile Communications Research Laboratory Southeast University Nanjing 210096 China School of Electrical and Information Engineering the University of Sydney NSW Australia

In this paper, we consider a *** *** ***(MIMO) relaying network with the ***(DF) protocol. Due to the *** transmissions, the *** from the relay transmitter to the relay receiver degrades the system performance. We thus propose an iterative beamforming structure(IBS) to mitigate the ***. In this method, the receive beamforming at the relay is optimized to maximize the ***(***), while the transmit beamforming at the relay is optimized to maximize the ***(***). To further improve the performance, the receive and transmit beamforming matrices are optimized between *** and *** in an iterative manner. Furthermore, in the presence of the residual ***, a *** ***(WF) maximum likelihood(ML) detector is proposed. In this detector, a WF is designed to transform a colored *** to a white noise, while the singular value decomposition is used to convert coupled spatial subchannels to parallelindependent ones. From simulations, we find that the proposed IBS performs much better than the existing schemes. Also, the proposed *** detector significantly reduces the complexity of the conventional ML(CML) detector from exponential time(an exponential function of the number of the source transmit antennas) to polynomial one while achieving a slightly better BER performance than the CML due to interference whitening.

Dear Editor,Short-range wireless communications have been widely used in our daily life,but the pursuit of a better communication experience never stops,leading to the more stringent requirements of emerging applications.^(1)For example,remote control applications such as telesurgery require a delay of less than 1 ms.^(2)Indus-trial closed-loop control applications such as automatic assembly lines have a reliability requirement of at least 99.999%.
