摘要
现代通信系统对数据传输速率的要求不断提高,在第三代移动通信系统TD-SCDMA中,一般意义的Turbo译码算法性能越来越不能满足实际的需要,通过研究Turbo码结构和编译码方法,对基于RADIX 4算法的Turbo译码进行了理论阐述和性能分析,结果表明新算法在复杂度和性能损失不大的情况下,译码速度和减少功耗方面有了较大的提高,证明该方法具有很好的实用价值。
With the upgrade requirement of high data transmission in communication system, the old turbo recursive algorithm does not satisfy the systemic needs in the mobile terminal system of TD-SCDMA. This paper introduces the principle of basic structure of Turbo codes. On the basis of analysis of the algorithm of Turbo code, this paper brings forward the method of a RADIX4 Turbo decoder and offers the resource consumed and the performance of the decoder, it proves that the way of implementation is of very high practical value.
