Interleaver Design for Parallel Convolutive Turbo Codes by the Genetic Algorithms

Abstract

Since them appearance in 1993, the turbo codes gives first best approaching to the Shannon limit, and a new direction for the channel encoding field, especially since they were adopted for multiple norms of telecommunications, such as deeper communication. To obtain an excellent performance it is necessary to design robust turbo code interleaver. We are investigating genetic algorithms as a promising optimization method to find good performing interleaver for the larger frame sizes. In this paper, we present our work, compare with several previous approaches and present some experimental results.
