Method of Experimental Estimating Processing Gain from Dispersion Correction in a Wideband Transionospheric Radio Channel

The paper is addressed to the problem of compensation for the energy losses caused by the second-order phase frequency dispersion in a transionospheric radio channel. To minimize losses, it is crucial to measure the characteristics of wideband channels and correct them for dispersion with the use of data gathered by GNSS/GPS navigation systems. Correction is reasonable when the processing gain from the correction exceeds a required threshold. The developed method allows to estimate the potential processing gain from the correction for dispersion distortions in transionospheric radio channels.
