Simulation and Evaluation of a DVB System using Simulink (Vol. I)

DVB (Digital video broadcasting) is the television digital systems. It's however much more than a simple replacement for existing analogue television transmission, this sytem has many advantages such as picture quality an allows you a range of new features and services including subtitling, multiple audio tracks, interactive content, multimedia content,...The system is based in the OFMD technology, which allows DVB system to exploit the spectrum frequencies in a better way, saving spectrum, but OFMD has an important drawback that is the peak to average power ratio problem. OFMD is based on the FFT algorithms generating several orthogonal subcarriers.This thesis talks about the improvement of the PAPR problem using the clipping method. The simulacion has been developed in Simulink and Matlab.
