A New Method of Turbo Decoding and Its Simulation

This paper researched on and simulated the traditional decoding method of Turbo codes.The time-lapsing of the traditional decoding method is great but its decoding rate is low relatively.In order to improve the performance and decoding rate and minimize the time-lapsing,this paper presents a new decoding method.According to the performance simulation and engineering realization,the advancement and realizability of this decoding method has been proved.At the same time,this paper compared this decoding method with the traditional decoding algorithm.By software simulation,this decoding method is proved to have a good performance and better practicability.
