Puncturing is a predominant strategy to construct high code-rate Turbo codes. Puncturing tables are crucial to the performance of punctured Turbo codes (PTC). This paper introduced the principles of punctured Turbo codes. Then it presented the conception of combining the designs of interleaver and puncturing scheme for punctured Turbo codes, and proposed a new design of interleaver and the relevant puncturing scheme. The computer simulation results show that the combined design performs excellently.
