                                                           ABSTRACT: OFDM otherwise called orthogonal frequency division multiplexing is a modulation and a multiple access technique that can be applied to mobile communications. OFDM or Multitone modulation as it is sometimes called is the basis for several commercial wireless applications. In OFDM the segments are according to frequency there by dividing the spectrum into a number of equally spaced tones, which are orthogonal with each other and carries a portion of user information on each tone. As the mobile cellular wireless system operates under harsh and challenging channel conditions, the wireless channel is distinct and much more unpredictable tha...
