This paper proposes the concept of inter-cell relay for downlink orthogonal frequency division multiple access(OFDMA)cellular systems,which uses multi-hop to relay calls from overloaded cells to light-load neighboring cells.It is shown that when using inter-cell relay,the number of calls in the congestion cell can be...

Cognitive Radio Network provides an opportunity to reduce the spectrum resource crisis by allowing secondary users to access the idle spectrum allocated to primary users.The precondition of spectrum sharing is to obtain the Spectrum Availability Information(SAI).Energy detection is a typical technology to get SAI.Wit...

This paper investigates the device-to-device(D2D)communication underlaying multi-user multi-input multi-output(MU-MIMO)cellular networks.It is assumed that D2D users reuse the downlink time-frequency resources of cellular links,and the base station(BS)is assumed to be equipped with multiple antennas.We investigate th...

Co-residency of virtual machines(VMs)of different tenants on the same physical platform would possibly lead to cross-VM side-channel attacks in the cloud.While most of current countermeasures fail for real or immediate deployment due to their requirement for modification of virtualization structure,we adopt dynamic m...

It’s a hot issue to improve the accuracy of network coordinate systems(NCS).By analyzing the error source of NCSes,it’s emphasized that guaranteeing the low dimensionality of embedding datasets is the principle on the designing of NCSes.Based on this observation,a PCA based Internet delay space dividing algorithm(I...

The quality of a multichannel audio signal may be reduced by missing data,which must be recovered before use.The data sets of multichannel audio can be quite large and have more than two axes of variation,such as channel,frame,and feature.To recover missing audio data,we propose a low-rank tensor completion method th...
