Abstract :
Different most used image watermarking scheme performances while transmitted over OFDM multi-path channels both with Doppler shift and without Doppler shift have been evaluated. Simulation results have shown that the system suffers from the Doppler shift and the watermarking performances are also decreased while the Doppler shift increasing.
