ofdm系统功能模块仿真（包含信道误码率等）(ofdm simulation system modules (including the bit error rate, etc.))

定义法计算计算Lorenz系统lyapunov指数，结果比较精确！ 可以改为任意3维动力系统的lyapunov指数的计算程序！(Define of the method to calculate the Lorenz system lyapunov index, accurate results! Can be changed to any 3-dimensional dynamical systems lyapunov index calculation program!)

image classification using SVM

现代信号处理的matlab开发软件包，包含很多常用的库函数(Matlab development of modern signal processing software package that contains a number of commonly used library functions)

说明：  卡尔曼滤波simulink模型，输入输出接口已经给出，给定观测向量和控制向量可以对状态向量进行估计(Kalman filter simulink model, input-output interface has been given, given the observation vector and control vector can be estimated state vector)

matlab code for audio compression

matlab程序设计，设计一个FIR滤波器加窗，并比较窗函数性能(FIR filter and compare the performance of the window function)

介绍了在提取穿越次数特征、粗网格特征以及密度特征提取的基础上应用SVM进行手写体阿拉伯数字识别的方法。(Introduced the extraction across a number of features, coarse grid and density feature extraction on the basis of the application of SVM method for handwritten digits recognition.)

双站交叉定位误差展示程序 产生观测数据 假设被定位对象匀速地从A点(dx1,dy1)运动到B点(dx2,dy2)，单位：km 使用速度输入V(km/h)，则dx2=V*t，t为观测时长(h) dy1=dy2=R，目标距离 假设采样时间间隔为1h(Bistatic cross-positioning errors show program)

说明：  搭建了精准的车辆模型，可以与Carsim中车辆模型进行对比，验证模型的正确性。(An accurate vehicle model is built, which can be compared with the vehicle model in Carsim to verify the correctness of the model.)
