Thedesignusesthedualinterleavingstructure,whichcangreatlyreduce the risk of the received information bits being erased in series caused by the burst error. As a result,the new Turbo code can achieve much improvement of correcting burst errorswithout additional delay.Simula鄄 tion results show that the dual interleaving Turbo code has better error correcting performance than the -6 commom Turbo code and the bit error rate can even reach 10 orders of magnitude.
