Secure Image Signal Transmission Scheme Using Poly-Polarization Filtering and Orthogonal Matrix

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 of states (PSs) (OMs) designed process symbols enhance protection PDL. Legitimate users able apply shared PSs OMs, step step, so could be recovered. However, for eavesdroppers, received signals random that difficult demodulate. bit error rate secrecy derived evaluate performance PPF-OM scheme. Finally, simulations demonstrated superior enhancing security eliminating
