An ionospheric model is a mathematical description of the ionosphere as a function of location, altitude, day of year, phase of the sunspot cycle and geomagnetic activity. Geophysically, the state of the ionospheric plasma may be described by four parameters: electron density, electron and ion temperature and, since several species of ions are present, ionic composition. Radio propagation depends uniquely on electron density. granum foundationWebtime. In our study the channel model is a simplified version of the Vogler and Hoffmeyer’s model [10] and does not take into account the altitude and propagation conditions. In the simulation of the HF ionospheric channel, the ITU-R approved Watterson Gaussian scatter model known as Watterson model is widely used.
