Error Correction With Chaotic Switching Between Convolutional Codecs

In this paper, a heterogeneous channel-coding scheme that combines a convolutional codec and a chaotic system into a single unit is proposed. The goal is to achieve a new coding technique that possesses the dual features of error correction and encryption. The proposed system is able to achieve reasonable error-correction performance when made to switch between optimal configurations. Its increased complexity makes it more secure relative to the conventional systems. Two additional systems that employ different chaotic switching methods are also proposed and studied. The investigation reveals the existence of tradeoffs between error-correction capability and the complexity of these systems.
