High quality and high speed multimedia services will be required in the next generation mobile communications. To satisfy these services, powerful error correction techniques are used. ARQ (auto repeat request) techniques, aspects of the throughput, and FEC (forward error correct) techniques have disadvantages in terms of reliability. H-ARQ (hybrid auto repeat request) systems have been studied extensively as a solution of these disadvantages. In this paper introduce double layer coding and H-ARQ type, proposed H-ARQ system using double layer coding methods. Simulate BER performance and Throughput. And we suggest that according to channel condition suitable H-ARQ type.
