C31. Efficient image transmission over the single carrier frequency division multiple access system using chaotic interleaving

Present day applications require various kinds of images and pictures as sources of information for interpretation and analysis. This paper studies the efficient image transmission over Single Carrier Frequency Division Multiple Access (SC-FDMA) system. In this paper, the performance of Discrete Fourier Transform (DFT) based SC-FDMA system and Discrete Cosine Transform (DCT) based SC-FDMA system is studied in order to select the proper technique for efficient image transmission. We also propose a chaotic interleaving scheme to be used with SC-FDMA for efficient image transmission. Simulation of both systems using Matlab program is presented, and the experimental results show that the DCT based SC-FDMA system achieves higher Peak Signal to Noise Ratio (PSNR) values in the received images than the DFT based SC-FDMA system due to its excellent spectral energy compaction property. Moreover, it uses only real arithmetics rather than the complex arithmetics used in the DFT based SC-FDMA system. Furthermore, the results show that the PSNR values are enhanced by the applying chaotic interleaving scheme in both systems.
