Quasilikelihood Estimate of the Number of Radio Signals with Unknown Amplitudes and Phases

Resumo

We perform synthesis and analysis of the quasilikelihood algorithm for estimating the number of signals. It is assumed that the signal parameters are known with accuracy up to a certain limited a priori interval. The estimation-algorithm efficiency is quantitatively characterized by the probability of signal-number estimation error. The analysis results are used to consider the possibility of employing the quasilikelihood algorithm for estimating the number of signals with partially unknown parameters.
