Parallel decodable turbo codes (PDTCs) are suitable for concurrent decoding and hence
have low latency. Memory collision issue is an important problem met during parallel
processing. In this article, we propose a collision free interleaver for parallel processing
operations. The performance of PDTCs is analyzed with the proposed random interleaver
preventing the memory collision problem. Distance spectra of PDTCs with the proposed
interleaver are computed and compared to those with S-random interleaver.
