Abstract

Orthogonal Frequency Division Multiplex (OFDM) is one form of a multicarrier modulation technique. It is implemented in high date communication systems. The data in OFDM is divided into groups of sub- streams. Each supstream is mapped into orthogonal subcarrier. Consequently, the period of symbol will be long enough and is not affected by multipath channel fading. OFDM provides high spectral efficiency as long as robustness to the fading channel which makes it desirable for any communication system but there are some drawbacks of the OFDM. One main defect of OFDM is the PAPR which causes inter-carrier interference and high out-of-band power which degrades the performance of OFDM such as BER and ISI. The mitigation of the PAPR’s impact is the goal of this paper in the case of WiMAX.
