Abstract This paper explores the impact of natural phenomena on signal data transmission across various ionospheric communication channels. The study focuses on three primary phenomena: meteor trails prevalent in the middle‐ and lower‐latitude ionosphere, bubble and plume structures observed around the equatorial ionosphere, and magnetic‐storm‐induced plasma structures excited at higher latitudes. These phenomena contribute substantially to two types of fast fading: flat and frequency‐selective. The relationships between signal intensity, signal intensity scintillation index, and the ‐factor of fast frequency‐selective fading are analytically derived. The mutual spectral characteristics of these parameters are also analyzed, considering their dependence on the carrier frequency of signals passing through channels affected by fading caused by natural clutter phenomena. Furthermore, the paper investigates the close relationship between the ‐factor of fast fading, which characterizes multiplicative noise, and data stream parameters such as capacity, spectral efficiency, and bit error rate. The effects of natural clutter phenomena on signal data transmission are analyzed across various ionospheric communication channels with fading at different latitudes. The study considers two practical frequency bands: HF , commonly used for “ionospheric weather” monitoring and ionospheric radiolocation using ionosondes, and UHF/SHF typically employed for land‐satellite communication links.
