说明：  采用贝叶斯正则化算法提高bp网络的性能，即L-M优化算法(The use of Bayesian regularization algorithm to improve network performance bp, that is, LM optimization algorithm)

内附收集的几种ldpc代码（编码解码皆有），另有论文及书籍（pdf格式）(Containing a collection of several ldpc code (codec Jieyou), while papers and books (pdf format))

Rls递推二乘最小算法的MAtlab 仿真。(Rls recursive least square algorithm MAtlab simulation.)

这个matlab程序实现了comtrade数据读出。(this program based on matlab realise exporting comtrade data)

本程序实现轨迹生成。基于的原理是飞行器位置和姿态解耦，对其进行独立设计，通过反解出惯性器件信息，从而用于导航。(The program trajectory generation. Based on the principle of the aircraft position and attitude decoupling its independent design, the inverse solution inertial devices used for navigation.)

设计一个按照时间抽取的基2快速傅里叶变换（基2FFT-DIT）。输入倒位序，输出自然顺序。(To design a time of extraction according to the base 2 Fast Fourier Transform (base 2FFT-DIT). Input inversion sequence, the output natural order.)
