In this paper, the realization of adaptive noise cancellation using an analogue neural network is discussed. The network is used to compute the coefficients of a linear transversal filter. The settling time decreases as the filter order increases. Owing to the real-time processing capabilities, the network can be used for fast adaptive noise canceller. The special properties of the tap input correlation matrix result in a cellular network architecture which greatly simplifies the VLSI implementation. Simulation results are given which point out very satisfactory performance.

A laser field that contains both additive and multiplicative noise are analysed based on a full saturation laser model. The numerical solution of intensity correlation time T c as well as the exact formulas of effective eigenvalue λ eff are calculated. Compared with the experimental measurements, excellent agreement is obtained for the full saturation laser theory, while relatively large errors occured in the third order laser theory and the measured data. By best fitting the experimental data of both T c and λ eff with the full saturation laser model, the cavity decay rate K of the laser system can be determined, therefore it provides a theoretical evidence for measuring K.

用全饱和激光模型对既含有加性又含有倍增噪声的激光场进行理论分析,求出了强度相关时间Tc的数值解和有效本征值λef的解析解。与实验测量相比较表明,全饱和激光模型与实验吻合得最好,而三次激光模型的偏差较大。当用全饱和激光模型的理论值同时拟合Tc和λef时,可以确定该激光系统的空腔衰减常数K,从而为测量K提供了理论依据
