摘要：
This letter presents an iterative decoding method for Reed-Solomon (RS) codes. The proposed algorithm is a stochastic shifting based iterative decoding (SSID) algorithm which takes advantage of the cyclic structure of RS codes. The performances of different updating schemes are compared. Simulation results show that this method provides significant gain over hard decision decoding and is superior to some other popular soft decision methods for short RS codes.
