  • Abstract Digital terrestrial video broadcasting system (DVB-T) uses a coded orthogonal frequency division multiplexing (COFDM) technology. Orthogonal Frequency Division Multiplexing is a multi-carrier modulation. Its data are spread to different frequencies and mutually orthogonal subcarriers. It has high efficiency of spectrum utilization, high rate transmission, against the selected channel frequency attenuation and resistance to multi-path interference, etc. characteristics of merit. In many studies it is assumed that there are interference and resulting in a reasonable source of interference, to simulate the real environment of the receiver channel signal. This thesis describes how to build DVB-T signal recording platform, and after correction of its basic performance of the receiver, through this platform to record the real environment of the received digital television base station signals, analyze the various responses, and by supporting analysis of the program to render the differences between theory and real.
