In this paper, the impact of carrier frequency offset (CFO) and CFO compensation on the transmission of encrypted images with different orthogonal frequency division multiplexing (OFDM) versions is studied. The investigated OFDM versions are the fast Fourier transform OFDM, the discrete cosine transform OFDM, and the discrete wavelet transform OFDM. A comparison between four encryption algorithms with images transmitted through different OFDM versions is presented. These algorithms are data encryption standard, advanced encryption standard, RC6, and chaotic Baker map. This comparison aims to select the most appropriate version of OFDM, and the most suitable image encryption algorithm for efficient image transmission. In the simulation experiments, the peak signal-to-noise ratio at the receiver is used as an evaluation metric for the decrypted image quality.

Abstract-Usage of image as data (or signal) is quite frequent in majority of the user-centric application. However, transmission of image over non-concrete communication medium like air is still vulnerable due to inherent weakness of wireless communication e.g. interference, noise, scattering, fading, security etc. Wireless image transmission has yet unsolved problems when it comes to error resiliency. In this paper, we have reviewed the significant research contribution published in last 5 years associated with wireless image transmission, channel coding mechanism, and investigated the scale of effectiveness in the techniques based on advantages and limitations. We also extracted a significant research gap, which requires immediate attention. Hence, we propose our future direction of work with an indicative architectural design in order to address the problems identified in research gap from existing literatures. This paper is meant to brief about the existing system and practical approaches to solve such problems.
