Chaos Encryption and Coding for Image Transmission Over Noisy Channel
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 6
Abstract
Abstract: The security and reliability of image transmission over wireless noisy channels are a big challenge. Ciphering techniques achieve security, but don’t consider the effect of errors occurring during wireless transmission. Error correction coding techniques must be used with ciphering to improve reliability and throughput. We will propose a combined ciphering and coding scheme based on the modified chaotic Logistic map with Low Density Parity-check Code (LDPC) as an error correction coding technique to overcome the limitation of wireless channel due to the factors that affect transmission such as noise and multipath propagation. The experimental results show that, this combined scheme enhanced the performance parameters such as PSNR and BER also achieved both security and reliability of image transmission through the wireless channel.
