OFDM (orthogonal frequency division multiplexing) is a multi-carrier modulation technology with great spectral efficiency that may be employed in multipath propagation. Because of its enticing characteristics, OFDM has been proposed as a modulation technology for a variety of global digital television terrestrial broadcasting (DTTB) systems. There are several frame structures proposed for efficient communication with numerous factor optimisations; however, there are always tradeoffs among the parameters. This research analysis is applied to discussed algorithms to determine the best outcome among them.
