摘要

This paper compares the quality of diffusion-based and permutationbasedrnencrypted image transmission using orthogonal frequency division multiplexingrn(OFDM) over wireless fading channel. Sensitivity to carrier frequencyrnoffsets (CFOs) is one of the limitations in OFDM transmission that was compensatedrnhere. Different OFDM diffusions are investigated to study encrypted imagerntransmission optimization. Peak signal-to-noise ratio between the original imagernand the decrypted image is used to evaluate the received image quality. Chaoticrnencrypted image modulated with CFOs compensated FFT-OFDM was found to givernoutstanding performance against other encryption and modulation techniques.
