In this paper, a novel secure image signal transmission scheme was proposed in wireless systems, which the poly-polarization filtering and orthogonal matrix (PPF-OM) were combined to protect eliminate polarization dependent loss (PDL) at same time, caused by non-ideal channel. This divided information sequence into two parts order modulate reshape results symbol matrices with size. Then, sets o...

The Transmission Line Matrix ( TLM ) is a physical discretization approach used to solve the wave equation numerically. The method replaces a continuous system by a network or an array of lumped elements. The TLM method involves dividing the solution region into a rectangular mesh of the transmission line segments. The nodes of the mesh are the points of discontinuity for acoustic impedances. A...
