Abstract: The principle of algebraic quadratic congruence mapping is analysed, and then limitation of odd-even protection and shift computation are added to the mapping of interleaver, and then a new improved algorithm for interleaver design is obtained. It is proved that the performance of the new algorithm is well by simulation.

Key words: Turbo code, quadratic congruence, interleaver, algebraic mapping
