中文说明：BP神经网络用于函数拟合与模式识别，调试通过可以使用，光纤陀螺输出误差的allan方差分析，可以得到很精确的幅值、频率、相位估计，包括调制，解调，信噪比计算，基于分段非线性权重值的Pso算法。
English Description：
BP neural network for function approximation and pattern recognition, through the debugger can be used, the analysis of the Allan variance of the output error of fiber optic gyroscope can get very accurate amplitude, frequency and phase estimation, including modulation, demodulation, signal to noise ratio is calculated, based on piecewise nonlinear weights of PSO algorithm.
