使用EM算法，估计16QAM调制方式下的信噪比(EM algorithm using the estimated signal to noise ratio under 16QAM modulation)

in this you can serialy transmit date from computer.image is first converted to gray and then transmitted colomn by colomn

实现数字图像水印的嵌入与提取，文件分为两个，一个为嵌入，一个为提取(digital image watermarking)

nvec_power: power supply driver for a NVIDIA compliant embedded controller.

this code is usefull for communication engineering

说明：  用pso对bp神经网络进行优化，对pid控制器进行优化设计(Using PSO to optimize BP neural network and PID controller)

This is matlab simulink svpwm model just copy and paste it in work and simulate.this is powerful modulation technique to reduce harmonics.the THD compared to other modulation techniques is also low .This technique includes analysis of sectors and determination of reference voltage vector and also angle calculation finally it is fed to two-level inverter

here i have attatched codes for pca image processing

基于Matlab中的simulink画一行随机数的频谱(Based on the spectrum of the random number draw a line in Matlab Simulink)

matlab查找单词系统 输入单词之后 会自动从库中查找单词(the systern of seraching words by matlab)
