IMAGE TRANSMISSION OVER RAYLEIGH FADING CHANNELS USING TURBO CODES WITH MULTI-DIMENSIONAL CHAOTIC INTERLEAVERS

Abstract

It is well known that the Turbo codes performance is considerably affected by its Interleaver design,which often has random permutation properties. In this paper we propose deterministic three types of 1-DChaotic Interleavers based on chaotic dynamics that have a random like behavior to give the Interleaver therequired degree of dispersion and correlation factors. Furthermore 2-D and 3-D Chaotic Interleavers are designedto have good separation parameters that have a major impact on the turbo codes performance especially overfading channels. Then, the designed chaotic Interleavers are compared with random one in terms of BERperformance for random data and measuring the quality of the received image in terms of their PSNRs. Theresults show that, the Multi-dimensional Chaotic Interleavers outperform the random one, in terms of both: BERand the quality of the received image.
