%X Orthogonal Frequency Division Multiplexing (OFDM) is a multi carrier modulation technique that provides highbandwidth efficiency because the carriers are orthogonal to each other and multiple carriers share the data amon g themselves. The main advantage of this transmission technique is its robustness to channel fading in wireless communication environment. This paper investigates the effectiveness of OFDM and assesses its suitability as a modulation technique in wireless communications. Several of the main factors affecting the performance of a typical OFDM system are considered and they include multipath delay spread, channel noise, distortion (clipping), and timing requirements. The core processing block and performance analysis of the system is modeled using Matlab.
