不考虑多径干扰时在高斯白噪声和瑞利衰落信道条件下QPSK的调制解调过程， 并采用准分析法完成误码性能的计算。仿真过程包括仿真信号产成，滤波器设置，QPSK调制，加入高斯白噪声，通过锐利信道衰落，QPSK解调，误码率计算等几部分(Not consider multi-path interference at the white Gaussian noise and Rayleigh fading channel under the conditions of the QPSK modulation and demodulation process and the use of quasi-analysis method to complete the calculation of BER. The simulation process includes the middle class into a simulation signal, filter settings, QPSK modulation, by adding Gaussian white noise, through the sharp decline in channel, QPSK demodulation, bit error rate calculation and other parts)

[Matlab]PCM Source code

该文档里面包含了MATLAB里常用的命令及例子，介绍的非常详细。(The document which contains a MATLAB command that is commonly used and examples described in great detail.)

一个单相逆变器，控制环路采用的是MATLAB里面的PID模块，有电流环和电压环，PWM发波模块采用的是MATLAB里面的PWM模块，省去了spwm的脉宽调制，需要在matlab2013中使用，较低版本没法运行(A single-phase inverter control loop uses PID module of MATLAB, current and voltage loop, a PWM wave module adopts the PWM module of MATLAB, eliminating the SPWM pulse width modulation and need to use in matlab2013, lower version did not run)

1-D Uniaxial-PML code

实现空间矢量控制，结果正确。经过验证！可放心使用！(Source link has yet to be found. Please, try to download it from local website.)

MATLAB的仿真，完整的OFDM系统,含Matlab仿真代码和DSP源代码，包括仿真和源程序，值得一看(MATLAB simulation, the complete OFDM system simulation with Matlab source code and DSP code, including simulation and source code, worth a visit)

here is the matlab plot of the few equation in mupad.this is the matlab tool which is used for 2d - 3d plots. even it is very useful solving equation by simple commands like solve.
