A major problem in telecommunications is to adapt the information to be transmitted to the propagation channel. This, in order to obtain a good quality of wireless communications with high transmission rates, and the release cable users to allow them to move in large buildings. In this type of communication systems must be properly fight one effect of multipath, specifically the frequency selective fading. This led to the development and use of the technique of multiplexing by Orthogonal Frequency Division Multiplexing (OFDM) appears to be a promising solution.
