Method of estimation of frequency parameters of ultra-wideband signals with an unknown spectrum shape in the presence of interference

Background. One of the urgent tasks of processing ultra-wideband signals is the assessment of their frequency parameters in complex signal-noise conditions. Aim. The paper presents the synthesis and analysis of an algorithm for jointly estimating the central frequency and bandwidth of ultra-wideband signals received against the background of Gaussian narrowband interference and Gaussian white noise. Methods. The study uses the computational method of statistical radiophysics and the method of mathematical statistics. Results. The characteristic of the joint estimation of the central frequency and frequency band of ultra-wideband signals, including the values of the offsets and scattering of the estimation, is found. It is established that with an increase in the intensity of interference, the accuracy of the joint estimation decreases. Conclusion. The obtained results allow us to make a reasonable choice of the necessary algorithm for estimating the frequency parameters of ultra-wideband signals depending on the requirements for the accuracy of estimates in a complex signal-noise environment.
