Method of Short Interleaver Design for Turbo Codes

  • The interleaver structure plays a very important role to the bit error rate performance of Turbo code. The periodic character of the feedback minimum polynomial and the divisibility character of the input information sequences were analyzed. Some interleavers were found that can change the divisible input sequences into indivisible ones, and the high Hamming weight codes can be obtained. A designing method for the short interleaver based on periodic character of the input information sequences is presented. It is proved to be an effective way by the simulation.
