摘要
通过对Turbo码的原有译码算法的研究和仿真,发现原译码算法延时较大、译码速率较低,为了改善译码性能,提高译码速率、减小译码延时,文章提出了一种新的译码算法,并进行了性能仿真和工程实现,证明这种译码算法具有良好的性能和实用价值,与原有译码算法比较,在性能上也有优越性。
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.
