非线性最小二乘优化问题，这里提供算法，供大家参考(Nonlinear least squares optimization problem, here are algorithms for reference)

ofdm信号模拟 16qam调制，解调，发送信号，接受信号，(ofdm signal simulator)

dct2的编程实现，用来压缩灰度图像，需要修改输入的图像名，保持和程序里的名称一致(dct2' s programming is used to compress grayscale images, need to modify the input image name, the name of maintaining and procedures where the same)

说明：  总体最小二乘法的ESPRIT方法，这种算法的估计精度明显好于原来的ESPRIT算法。可以很好的估计出信号的角度。仿真中用的是均匀阵列。(Total least squares method of the ESPRIT method, the algorithm of the estimation accuracy significantly better than the original ESPRIT algorithm. Can be a very good signal to estimate the angle. Simulation using the uniform array.)

包含一些通信系统的仿真程序 包括时间分集，频率分集，二时二频分集(Communication system contains some simulation program including time diversity, frequency diversity, frequency diversity two two)

固体力学的大作业，有限元法计算阶段梁，包括了计算单元应力。(Finite Element Method matlab program, an example of 1D step beam element. Including calculation of elemental stress.)

this was my homework in the lesson "digital image processing" it is my own average and median filters function without useing the matlab s original functions . it can help your learning about filters. i uploaded whole the material but you can find it completely in "ö dev2.docx" my whole homework.

进化差分算法，遗传算法的分支，非常好，值得学习( model and its detailed introduction matlab realize)

淘宝里卖的mpu6050模块，采用硬件卡尔曼滤波直接输出姿态角，省去大家复杂的IIC编写 (mpu6050 Data processing)
