A Simulation of Image Transmission: Turbo Codes Combined with JPEG Image Compression

Authors : A. Moulay Lakhdar , R. Meliani and M. Kandouci

Abstract: An investigation of Unequal Error Protection (UEP) methods applied to JPEG image transmission using turbo codes is presented. The JPEG image is partitioned into two groups, i.e., DC components and AC components according to their respective sensitivity to channel noise. The highly sensitive DC components are better protected with a lower coding rate, while the less sensitive AC components use a higher coding rate. While we use the s-random interleaver and s-random odd-even interleaver combined with odd-even puncturing, we can fix easily the local rate of turbo-code. We propose to modify the design of s-random interleaver to fix the number of parity bits. Simulation results are given to demonstrate how the new UEP schemes outperforms the Equal Error Protection (EEP) scheme in terms of Bit Error Rate (BER) and Peak Signal to Noise Ratio (PSNR).
