用MATLAB程序打开数字地震数据记录SAC格式。(using Matlab, it can open the data of seismic wave.)

说明：  熟悉OQPSK的基本原理、调制解调技术，掌握MATLAB中M文件的使用及相关函数的调用方法(The goal of this design is to deeply understand the basic principle of OQPSk modulation and demodulation, learn how to use MATLAB software in the M file to realize OQPSk modulation and demodulation analysis and join the influence of different noise on the signal, the first to create a digital baseband signal and then the corresponding function in MATLAB the baseband signal modulation, and then analyses the waveform of the modulated, record the results of modulated signals after demodulation, observe the demodulation results and record, finally adding noise in the signal and then observe the changes of the time-frequency diagram,)

基于粒子滤波的故障检测，使用状态估计和残差平滑的方法(Particle filter-based fault detection, the use of state estimation and residual smoothing method)

这是一个关于图像自动分割的程序，效果不错哦 (This is an automatic segmentation procedure on the image, the effect is good, oh)

matlab source code for neutral fuzzy system

Code for denoising images. This code differs from standard wavelet denoising techniques in that it uses non-orthogonal wavelets, and unlike existing techniques, ensures that phase information is preserved in the image. Phase information is of crucial importance to human visual perception. Also, this code does have an effective way of determining threshold levels automatically. (Code for denoising images.

Sample Matrix Inversion is implemented via matlab. the code plot the SINR performance as a function of BER and compare it to the theoretical upper bound BER. YOU CAN CHANGE THE PARAMETERS AND TEST THE RESULTS.
