JPEG图像压缩标准MATLAB仿真程序。包括DCT变换及其逆变换、量化及反量化等过程。(JPEG image compression standard MATLAB simulation program. Including the DCT transform and its inverse transform, quantization and inverse quantization and other processes.)

ofdm发送端和接收端，根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。(ofdm sending end and receiving end, according to the characteristics of the short training word correlation operation, the signal reaching the detector, when the detected correlation value is greater than the threshold after a certain number of times that a signal arrives.)

As a consequence, more exact models of devices can be retained for analysis rather than the approximate models commonly introduced for the sake of computational simplicity. A computer icon appears in the margin with each introduction of MATLAB analysis.

计算关联度，本方法使用的是归一化的方法，和传统的经典关联度计算方法相比较，增加了对各个权重的分析和计算，使结果更加有说服力。(Correlation calculation, this method uses the normalized method, and the traditional classical correlation method compared to an increase of weights of the various analysis and calculations makes the results more convincing.)

：SPWM调制技术是通过改变输出方波的占空比来改变等效的输出电压，其调制波为正弦波，脉冲宽度间占空 比按正弦规率排列， 这样输出波形经过适当的滤波可以做到正弦波输出。它广泛的用于支流交流逆变器。本次实 验使用Matlab/Simulink对SPWM技术进行仿真并分析数据。(: SPWM modulation by changing the duty cycle square wave output to change the equivalent output voltage, the modulated sine wave, pulse width, duty cycle between the rate at sine arranged so that the filter output waveform can be done properly to the sine wave output. It is widely used in branch AC inverter. The experiment uses Matlab/Simulink simulation of the SPWM technique and analyze data.)
