  "abstract": "<p>A method to design efficient puncture-constrained&nbsp;interleavers for turbo codes (TCs) is introduced. Resulting TCs&nbsp;profit from a joint optimization of puncturing pattern and&nbsp;interleaver to achieve an improved error rate performance. First,&nbsp;the puncturing pattern is selected based on the constituent&nbsp;code Hamming distance spectrum and on the TC extrinsic&nbsp;information exchange under uniform interleaving. Then, the&nbsp;interleaver function is defined via a layered design process&nbsp;taking account of several design criteria such as minimum span,&nbsp;correlation girth, and puncturing constraints. We show that&nbsp;applying interleaving with a periodic cross connection pattern&nbsp;that can be assimilated to a protograph improves error-correction&nbsp;performance when compared to the state-of-the-art TCs. An&nbsp;application example is elaborated and compared with the long&nbsp;term evolution (LTE) standard: a significant gain in performance&nbsp;can be observed. An additional benefit of the proposed technique&nbsp;resides in the important reduction of the search space for the&nbsp;different interleaver parameters.</p>",
