WebN2 - The objective of the work proposed here is to analyze OFDM system behavior in Digital Video Broadcasting (DVB-T) systems at both transmission and reception levels and improve its performance. OFDM analysis is crucial because it solves a very critical problem encountered in wireless communications. WebDVB-SH architectures OFDM (Orthogonal Frequency Division Multiplexing) is the natural choice for terrestrial modulation and is the basis of both the DVB-H and DVB-T systems. DVB-SH introduces a second scheme, a Time Division Multiplex (TDM), leading to two reference architectures termed SH-A and SH-B:
