摘要: A Gaussian frequency-domain maximum likelihood estimator (MLE) to estimate the transfer function of linear continuous-time systems with time delay is presented. The stochastic framework an errors-in-variables model, which means that input as well output system disturbed noise. applied a practical measurement problem, namely estimation location discontinuities, e.g. faults in electrical cables from reflectogram. Experimental results for coaxial lines show it possible identify simultaneously discontinuity and rational approximation generator mismatch, fault impedance, some cable parameters. >
