Amplitude estimate of the ultra wide band quasi radio signal with unknown initial phase and duration

Abstract

We considered the new quasi-likelihood amplitude estimate algorithm for the ultra wide band quasi radio signal with unknown initial phase and inaccurately known duration against white Gaussian noise. Its block diagram was presented in single-channel units. We found the statistical characteristics of the introduced estimate and we also investigated the influence of the prior signal duration ignorance on the estimation efficiency. We determined the loss in accuracy of the amplitude estimate because of the duration-offset replica.
