Throughout the past decade, the discovery of turbo codes has been considered as one of the most successful researches whose impact significantly enhanced the quality of modern communication systems. Turbo codes offer the best compromise between structure (concatenation) and randomness created by the interleaver. Our research and development has been focused on the area of turbo code interleaver optimization in the recent time. We have investigated the ability of genetic algorithms, perhaps the most used nature-inspired optimization technique, to find a turbo code interleaver with above average performance. A new modification of genetic algorithms, designed to deal with constraints of a combinatorial optimization problem such as interleaver optimization task, was developed. (en)
