摘要
LTE系统对可靠通信提出了更高的要求,这在一定程度上依赖于信道编码的性能。针对LTE系统中的Turbo译码算法进行了研究,在Max-Log-MAP和Log-MAP算法的基础上提出了一种改进算法。理论分析和仿真结果表明,这种改进算法的性能有进一步提升,并且更加易于硬件实现,具有较低的复杂度。
LTE system requires reliable communication of higher standard,which depends on channel coding performance to some extent.In this paper,decoding algorithm of Turbo codes in LTE system is researched and an improved algorithm is presented based on the Max-log-MAP and Log-MAP algorithms.Theoretical analysis and simulation result show that the performance of this improved algorithm is promoted ulteriorly,it is easy to hardware implementation and has lower complexity.
