摘　　要：通过对咬尾卷积编码的原理分析,分析验证了咬尾卷积编码在几种不同信道下的性能,提出了一种基于DSP的编码实现方法,将该程序在CCS3.3中运行,验证了程序的可行性、高效性。最后通过Matlab探究现有的几种咬尾卷积译码的性能,得到一种可靠的译码方式。该方案已应用到LTE-TDD无线综合测试仪表的开发中。Through the analysis of tail-biting convolutional coding theory,a validation of the tail-biting convolutional coding in several different channel performance is presented. Then a encoded method based on DSP which runs in CCS3.3 to verify the fea- sibility of the program. Finally explore several existing tail biting convolutional decoding performance through matlab, to get a reli- able decoding method. This program has been applied to LTE-TDD wireless integrated test instrument development.
