Broadband Noise-like Signal Parameters Joint Estimation Quality with Dispersion Distortions in the Ionospheric Channel

Abstract

The article conducted a theoretical study of the quality of a joint estimation of four parameters of a broadband ionosphere distorted signal, namely: the slope of the dispersion characteristic, Doppler frequency shift, delay, and phase shift. In this case, quality is understood as the dependence of the standard deviation and cross-correlation of the estimates on the signal-to-noise ratio. The article obtained theoretical expressions for variances and cross-correlations of the estimates of the above unknown parameters, as well as investigated their sample values during simulation.
