S-Distance Based Deterministic Block Parallel Interleaver for Turbo Codes

摘要

In this paper, an improved deterministic block parallel interleaver based on S-distance for Turbo codes is designed according to the theory of Bubble Sort. The aim is to overcome the long delay of S-random interleaver. The improved interleaver has the larger spreading factor 'S', lower delay and better bit error rate performance, as well as it requires less memory hardware. Simulation results verify the effectiveness of the S-distance based interleaver for Turbo codes.
