New puncturing pattern for bad interleavers in turbo-codes

This paper presents a new method of puncturing for worst interleavers. We study via simulation the effect of different combinations of tow puncturing patterns and three classes of interleavers on the performance of punctured turbo-coded systems. The interleavers types are uniform, S-random and odd-even random. The effect of new puncturing pattern is evaluated and shown to be ameliorated the performance of turbo-coded systems.
