Webtime. 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. This model assumes that WebAs a three-dimensional and time-dependent model, it has the capability to provide vertical or slant ionospheric delay correction by integrating the predicted electron density along the line of sight vector between satellite and receiver.
