تصميم مشذر لترميزات تربو بالاعتماد علي تحليل اداء الترميز

The interleaver is a key component of Turbo codes and its design is essential for achieving high performance in these codes. I present in this research an interleaver design algorithm using the proposed representing algorithm of fractional numbers, turbo encoding algorithm, and their procedures. The weight distribution as design criterion is presented. The complexity of the algorithm presented in this research arises from interleaver length. The qualities of the algorithm is demonstrated by comparing the weight distributions of various Turbo codes using a number of previously proposed interleaver techniques (pseudo random, non uniform, and block Helical simile) which is achieved good distance properties, and high performance of turbo codes.
