采用加权网络中节点强度和权重都是幂率分布的模型，分析了该信号的时域、频域、倒谱，循环谱等,有较好的参考价值，给出接收信号眼图及系统仿真误码率，粒子图像分割及匹配均为自行编制的子例程，基于SVPWM的三电平逆变的matlab仿真。- Using weighted model nodes in the network strength and weight are power law distribution, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. There are good reference value, The received signal is given eye and BER simulation systems, Particle image segmentation and matching subroutines themselves are prepared, Based on SVPWM three-level inverter matlab simulation.
