摘要
Abstract
In one dimensional signal processing model, we present robust estimates for parameter amplitudes via constructing a two-step estimation procedure. For certain pre-specified consistent estimators of frequencies, we plug them into the M estimation equations in step one. Subsequently, we obtain M estimators for parameter amplitudes, which are consistent. Simulation studies show that the two-step estimator performs better than the traditional least squares estimator.关键词
