BPSK BER MATLAB Simulink and Theory

This code simulates QPSK modulation on base band. This code has been written on Matlab and it will be very useful I think! :)

Generalised Cross Correlation Algorithms. It is useful to estimate the time delay in almost all situations

这是国标数字电视地面传输中生成矩阵的生成程序，只要按照MATLAB的格式输入国标附录1中的数据，就可以生成完整的G矩阵(This is the national standard of digital TV terrestrial transmission matrix generated in the generation process, as long as the input in accordance with the format of MATLAB Appendix 1 GB of data, we can generate the complete G matrix)

Arnold置乱变换的matlab代码，函数形式，做数字水印经常用到。(Arnold scrambling transform matlab code, functional form, so often used in digital watermarking.)

这是关于瑞利衰落信道的matlab仿真程序(on Rayleigh fading channels Matlab simulation program)

please do not put files on these

绘制极坐标图函数，绘制多条时，是将参数组成行向量(Draw polar plot function to draw multiple parameters composed of row vectors)

This circuit uses the AC6 block of SimPowerSystems™ library. It models a permanent magnet (PM) synchronous motor drive with a braking chopper for a 3HP motor. The PM synchronous motor is fed by a PWM voltage source inverter, which is built using a Universal Bridge Block. The speed control loop uses a PI regulator to produce the flux and torque references for the vector control block. The vector control block computes the three reference motor line currents corresponding to the flux and torque references and then feeds the motor with these currents using a three-phase current regulator.

用FORTRON程序编的最速下降法，用来解决无约束规划问题(With FORTRON program compiled the steepest descent method, which is used to solve the unconstrained programming problem)
