25th Signal Processing and Communications Applications Conference (SIU), Antalya, Turkey, 15 - 18 May 2017
In this study, we have investigated the spatial spectral analysis of the ionosphere using Total Electron Content(TEC) maps. In order to observe the ionospheric disturbances and variations, the Discrete Cosine Transform(DCT) is applied to TEC maps over the mid-latitude region and observed results are investigated further.
