基于SVPWM的三电平逆变的matlab仿真，采用波束成形技术的BER计算，直线阵采用切比学夫加权控制主旁瓣比，实现了对10个数字音的识别，使用高阶累积量对MPSK信号进行调制识别，采用了小波去噪的思想。- Based on SVPWM three-level inverter matlab simulation, By applying the beam forming technology of BER Linear array using cut than learning laid upon the right control of the main sidelobe ratio, To achieve the recognition of 10 digital sound, Using high-order cumulants of MPSK signal modulation recognition, Using wavelet denoising thought.
