基于无线传感器网络的水下目标识别，调制线谱特征提取(Underwater wireless sensor network based object recognition, feature extraction line spectrum modulation)

说明：  单极型倍频SPWM simulink仿真，和同等单极性SPWM相比，相同的开关频率，输出电压THD更低，逆变器输出可使用更小的滤波器，对逆变器体积的降低很有帮助，封装子系统，调制度、载波比和调制频率可自由调节，简单易用。matlab版本：2015b(Compared with the same unipolar SPWM, the same switching frequency and output voltage thd are lower. The output of the inverter can use smaller filters, which is very helpful to reduce the volume of the inverter. The package subsystem, modulation system, carrier ratio and modulation frequency rate can be adjusted freely and easy to use. Matlab version: 2015b)
