Mitigation of Dispersion Distortions of Transionospheric Communication Channels when Total Electron Content Measurements are Corrupted with Stochastic Error

The paper addresses the problem of mitigation of dispersion distortions in transionospheric satellite communication channels with the use of the data on the propagation medium obtained from global navigation systems. Distortions mitigation is performed by a correction device that operates in the following modes: compensation for dispersion, channel sounding, equalizer training. In addition to this, the influence of stochastic errors that corrupts the total electron content (TEC) measurements on the dispersion correction was considered. The full-scale experiments carried out in Yoshkar-Ola allowed to produce daily variations in the total electron content, frequency dispersion parameters and channel lifetime with the use of data from the GLONASS / GPS satellite systems.
