Quasi-likelihood frequency estimation algorithm of an ultra-wideband quasi-radio signal with unknown duration

The quasi-likelihood frequency estimation algorithm of an ultra-wideband quasi-radio signal with unknown duration, observed white Gaussian noise, is studied. When synthesizing the algorithm, instead some its expected value was used. dependence variance estimate on signal-to-noise ratio for various values duration detuning and bias narrowband parameter are obtained. It has been established that a significant effect efficiency signal, while at large parameter, obtained expressions coincide known radio signal. Recommendations use synthesized in practical applications formulated.
