On the Transmission of Double Watermarked Image over Rician FSO Channel
Keywords:FSO transmission, Rician channels, watermarking, image processing, discrete wavelet transforms
Performance analysis of double watermarked image transmission over the Rician turbulence FSO channel was carried out in this paper. First, we have considered the importance of copyright, robustness of watermark in FSO transmission and presented some algorithms for watermarking. Then, simulation of FSO transmission of double watermarked image over Rician channels has been carried out and obtained simulation results have been shown graphically. Quality of the extraction of the primary watermark and the secondary watermark was discussed in the function of FSO channel link parameter K value.
