分块并行结构的Turbo译码算法研究

Study of the Algorithm for Turbo Decoding of Sub-blocks Parallel Structure

分析了两种分块并行Turbo译码算法,并提出了一种新型的混合算法。研究表明,与现有的两种算法相比,混合算法融合了两者的优点,虽多消耗了少量资源,但是明显改善了译码性能。

In this paper,two Turbo decoding algorithms of parallel sub-blocks are analyzed,and a novel hybrid algorithm is proposed.It is shown that,compared with the existing algorithms,the proposed hybrid algorithm combines their advantages and significantly improves the decoding performance at a cost of little more resource consumption.
