In practice, fading channel coefficients are estimated imperfectly at receivers. In this paper, I propose and analyze a cooperative communication scheme under physical layer security with imperfect CSI. In this scheme, a source node transmits secure data to a destination node D with a help of a relay node against an eavesdropper node without direct links of source-destination and source-eavesdropper.

In this paper, we propose a novel method to estimate and remove the jamming signals from multiple multi-antenna jammers in a two-way relay network with multi-antenna legitimate and relay nodes. We carefully consider the signals in the time slots in order to exploit the repetition of the signals and design the transmitted signals which can work in different cases.

The quasi-3D shear deformation theory, which takes the thickness stretching effect into account, is adopted to formulate a finite element formulation for computing vibration characteristics. The accuracy of the derived formulation is confirmed through a comparison study. The numerical result reveals that the foundation supporting area plays an important role on the vibration behavior of the plates, and the effect of the layer thickness ratio on the frequencies is governed by the supporting area.

The element using hierarchical functions to interpolate the displacements and rotation is efficient, and it is capable to give accurate dynamic responses by small number of the elements. The effects of the moving mass parameters, material distribution, layer thickness ratio and inclined angle on the dynamic behavior of the FGSW beam are examined and highlighted.

The effect of the periodic oscillation of the gravitational field, known as g-jitter, on the free convection from a vertical plate is investigated in the present paper. The problem has been simplified by the laminar boundary layer and Boussinesq approximations. The fully implicit finite-difference scheme is used to solve the dimensionless system of the governing equations. The results for laminar flow of air (Pr = 0.72) and water (Pr = 7.00) are presented for different values of the amplitudes and frequencies of the g-jitter.

The Digital Video Broadcasting Next Generation Handheld (DVB-NGH) standard has adopted many advanced technologies, including overhead reduction schemes, to maximize the system capacity. However, some of the overhead reduction schemes of Layer-l (LI) signaling result in increased initial capture time delays. In order to get a more flexible trade-off between overhead reduction and initial capture time delay, a full-truncated Ll signaling scheme is proposed in DVB-NGH systems. Simulation results demonstrate the effectiveness ofthe proposed scheme.

Ground improvement technique by prefabricated vertical drain (PVD) in combination with vacuum preloading is widely used to facilitate consolidation process and reduce residual settlement. However, this technique seem hardly be estimated by both analytical method and numerical method because it has complex boundary conditions (such as vacuum pressure changing with time). Moreover, lateral displacements caused by this technique are also significant problem.
