摘要：

针对3GPP最新发布的LTE-A Release10标准，通过对两种常用内交织算法的研究分析，权衡时间复杂度和存储量，选择了一种最适合TD-LTE无线综合测试仪表的内交织算法，并通过TMS32064x DSP实现。基于集成化开发环境CCS3.3，编程实现LTE-A Turbo内交织计算，运行结果验证了查表生成法的可行性、高效性。

关键词: LTE-A, 循环迭代法, 查表生成法, DSP实现

Abstract:

Based on the recently released LTE-A（long term evolution-advanced）R10 standard by 3GPP,this paper researched two internal interleaver algorithms which were used commonly.Balancing the complexity of the time against memory space,it choosed the most suitable internal interleaver algorithm for the TD-LTE wireless integrated test instrument,and realized the algorithm in the TMS32064xDSP.The operation results of the Turbo internal interleaver program in CCS3.3 verify that the checking table created arithmetic is feasible and effective.

Key words: long term evolution-advanced, cyclic iterative arithmetic, checking table created arithmetic, DSP realization
