In this paper, the authors investigate the effectiveness of Orthogonal Frequency Division Multiplexing (OFDM) as a modulation technique for wireless radio application. Orthogonal frequency division multiplexing has numerous exclusive properties which erects it particularly well suited to grip the challenging ecological/environmental circumstances experienced by mobile wireless data application. It was originated that OFDM performs extremely well compared with CDMA providing a very high forbearance to multipath delay spread, peak power clipping and channel noise. Also it endows with a high spectral efficiency.
