The main objectives of this thesis are: (1) investigate the effectiveness of orthogonal frequency division multiplexing (ofdm) as a modulation technique for wireless radio applications main factors affecting the performance of an ofdm system are multipath delay spread and channel noise. However, ofdm faces the peak-to-average power ratio (papr) problem that is a major drawback of multicarrier transmission system which leads to power inefficiency in rf section of the transmitter.
