This dissertation investigates the performance of the second-generation terrestrial digital video broadcasting system (DVB-T2) over doubly selective fading channels, which are characterized by their variability in both frequency and time. Such channels are particularly relevant in mobile reception scenarios where the signal quality can be significantly impacted by factors like multipath effects and Doppler shifts. The research involved extensive simulations to evaluate how various modulation and coding strategies affect the bit error rate (BER) and signal quality under different fading conditions. The findings provide a comprehensive analysis of DVB-T2 capabilities in handling complex channel conditions, offering valuable insights for the enhancement of broadcast system design tailored to dynamic environments. The results demonstrate the robustness of DVB-T2 in maintaining signal integrity, thereby supporting its application in modern digital broadcasting setups.
