Abstract
In this paper, a numerical density function of impulsive symmetric α-stable noise was presented and simulated in the turbo coding environment. The impulsive symmetric α-stable noise has no closed-form expression, making it difficult to realize in its original form. The impulsive symmetric α-stable noise can be used to approximate many kinds of noise sources when all the parameters of the function are well optimized to a specific value. In this paper, one of the parameters is set to a specific value so that the stable distribution approximates Cauchy distribution. Correspondingly, it is applied on turbo codes. 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 proposed hybrid interleaver outperforms the existing techniques.
