说明：  Turbo code primer用于通信系统里编码译码，误码率小，但复杂度比较高。(Turbo code primer is used for coding and decoding in communication systems, with low bit error rate but high complexity.)

基于灰色关联分析在MATALAB中的应用程序算法(Gray Theory)

控制理论算法在采用状态反馈对目标进行控制时，往往忽略了时滞的存在。时滞往往存在于真实的系统中，而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论，以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)
