Abstract:

Quasilikehood and maximum likelihood algorithms for estimating the regular radiosignal duration with a partially unknown amplitude and initial phase. It was assumed that the decisive statistics twice differentiable in the unknown parameters. Characteristics of the synthesized algorithms are found. The found values of the detuning amplitude and initial phase in which quasilikehood algorithm for estimating the duration has higher accuracy than maximum likelihood.
