Hello friends! Today, we will study a MATLAB project for modelling a DVB-T2 transmission system using consistent channel frequency responses. The main question is simple: when we compare two transmitter configurations, how can we make sure that a different random channel has not decided the result for us? We will follow the original project from its parameter-selection interface to its BER plots, then improve the experiment design through repeated trials and confidence intervals. Along the way, I will explain the difference between a channel realization and a received waveform, because confusing these two quantities makes a comparison unreliable. The original screenshots are retained as historical project results. Some settings and statistical labels in the earlier report were inconsistent ...
