解耦，恢复原信号，针对EMD方法的不足,包括最小二乘法、SVM、神经网络、1_k近邻法,最大似然（ML）准则和最大后验概率（MAP）准则，有借鉴意义哦，采用波束成形技术的BER计算，光纤陀螺输出误差的allan方差分析。- Decoupling, restore the original signal, For lack of EMD, Including the least squares method, the SVM, neural networks, 1 _k neighbor method, Maximum Likelihood (ML) criteria and maximum a posteriori (MAP) criterion, There are reference Oh, By applying the beam forming technology of BER allan FOG output error variance analysis.
