摘　　要：为在TI多核DSP平台协处理器TMS320C6670上实现LTE模式下的Turbo译码,了解了CTC Turbo译码器原理的同时对几种常用的CTC Turbo译码算法进行了研究。另外研究了TMS320C6670的协处理器TCP3D,在了解了其一些重要的工作特性后,结合其采用的译码算法,深入了解了其实现CTC turbo译码的具体实现流程,并得以工程实现。为验证TCP3D LTE模式下的CTC Turbo译码的实用性,进行了译码性能测试,并得到了不同业务速率的误码率曲线图。In order to realize Turbo decoding in LTE mode on TI multi-core DSP platform coprocessor TMS320C6670,while understanding the principle of CTC Turbo decoder,several commonly used CTC Turbo decoding algorithms are explored,and TCP3D coprocessor from TMS320C6670 series also discussed.After introducing some of its important working characteristics,combined with the decoding algorithm it uses,this paper describes in depth the specific implementation process of CTC turbo decoding and in particular,its engineering realization.In order to verify the practicality of CTC Turbo decoding in TCP3D LTE mode,the decoding performance test is done,and the BER(bit error rate)curves for different service rates are acquired.
