摘    要:提出采用投影寻踪网络逼近Volterra滤波器的方法以实现光纤陀螺输出信号非线性噪声消除.投影寻踪网络采用批量学习和参数交替优化的训练算法,可以自适应确定神经网络的规模、参数和神经元函数,具有简捷的网络结构和较强的鲁棒性,克服了Volterra滤波器随着阶数增加,滤波系数的数量呈几何级数增长,实现困难的问题.仿真结果表明PPLN网络滤波器比Volterra滤波器具有更好的消噪效果.

关 键 词:光电子学  光纤陀螺  投影寻踪网络  Vloterra  滤波器  噪声

Abstract:To cancel nonlinear noise of fiber optical gyroscope's output signal.A projection pursuit learning network was developed to approach the Volterra filter.The PPLN uses the batch learning technique and parameter optimized alternately to acquire adapting networks size,weights and hidden unit functions,hence can obtain simpler architecture and good robustness.It was to overcom problem that number of the Volterra filter coefficients assumes a geometric series increase with the increasing of the filter order,it i...
