| 摘 要： | IntroductionTurbo codes, first introduced by Berrou et al.[1],have attracted the attention of many researchers for theirremarkable coding gains close to theoretical limits, yetadmitting a relatively simple iterative decodingtechnique[2]. Since then, abundant of fruitful results on theperformance of turbo codes have been published, in whicha distance spectrum interpretation was presented by [3]and a super trellis structure of turbo codes was derived by[4]. An analytical…

| Abstract: | Currently puncturing is the predominant strategy to construct high code rate turbo codes. The puncturing period and puncturing patterns, which have important effect on the performance of punctured turbo codes (PTC), yet have not received complete investigations, are addressed in this paper. Proposes on selecting puncturing period and puncturing patterns are presented. Since puncturing will alter the distance spectrum of turbo codes, the performance of PTC needs further consideration. We derive an analytical upper bound for PTC, based on the assumption of uniform puncturing defined in this paper. Finally, we present some numeric results on the performance of PTC. |
