Performance Enhancement of Chaotic Error Correction Coding Using Consecutive Sequences

The use of chaotic dynamics for error correction is the subject extensive research, as approach allows to avoid redundant data. This work proposes a new technique non-coherent chaos communications modifying error-correction depending on dynamics. In proposed system, there are two consecutive sequences created from comparable map, with second series being latest value initial one. Generation sequential sequence dynamic delivers additional information receiver, allowing it appropriately recover and, hence, facilitate receiver’s bit-error performance. For and detecting symbol that transmitted, suboptimal based nearest distance between map trajectories over n-dimensional received utilized. Simulation results show improves Eb/N0 dimension trajectory increases, indicating method overall With 4, gain 0.8 dB in achieved compared an without any error-correcting schemes, at probability 10−3.
