Abstract: In this paper, a numerical density function of Impulsive symmetric α-stable (ISAS) noise was presented and simulated in the turbo coding environment. The ISAS noise has no closed-form expression, making it difficult to realize. The ISAS noise can be used to approximate many kinds of noise sources. In this paper, one of the parameters is used to set it as the Cauchy distribution. In addition, an improved interleaver structure is presented where the multiple interleavers of smaller capacity replace a single epic interleaver. Simulation results show that the hybrid interleaver outperforms the other interleavers presented in this paper.
