Research on the Performance of Different Interleavers in Turbo Coding

There are many factors that affect the Turbo code in Turbo coding process, which the design of interleaver and interleaving depth impact very large for Turbo coding performance. Now, there is not only no comprehensive and systematic research of interleaver, but also no clear concept about the performance impact of interleaver at different interleaving depth. This paper introduces the principle of common interleaver. Then the impact of different interleaver and the performance impact of interleaver at different interleaving depth are discussed with Matlab simulation for Turbo coding.
