| Abstract: | The discovery of Turbo Code has developed a new scope of communication coding field.In this paper,several kind of interleaver that designed for Turbo Code was compared by computer simulation at different interleaver size using MATLAB tools.Two crierions for interleaver design were also discussed,which can be used to improve the performance of Turbo Code.And the criterion was verified by simulation focus on performance of SP interleaver .The paper indicates that the design of interleaver should aim at better performance of the code. |
