Interleaver Design for Turbo-Based Distributed Video Coding

The function of interleavers in turbo codes are analyzed and the disadvantages of some existing interleavers are pointed out. Two novel interleavers, named block-based S-random interleaver (BSI) and pseudo random-based S-random interleaver (PRSI) respectively, are designed and simulated. Compared to some existing interleavers, the designed interleavers have better performance in aspects of iteration times of turbo decoding and latency. Simulation results indicate that the proposed interleavers are effective when employed in turbo-based distributed video coding.
