Keywords:
AWGN, CCDF, IFFT, OFDM, PAPR, QPSK.Abstract
WiMAX which represents World Interoperability for Microwave Access is a major part of broadband wireless network (BWN), having IEEE 803.16 standard provides innovative fixed as well as mobile platform for broadband internet access anywhere in anytime. It is Wireless communication systems can be found all around the world today. It works on high data rate and it is a wireless technique so fading and attenuation in the signals is presence due to noise, inter symbol interference, inter carrier interference etc. OFDM modulation technique is used to work on multicarrier. OFDM works on orthogonality so presence of ISI is neglected. In this project, we analysis of the original OICF algorithm can achieve the desired PAPR while the simplified one exhibits almost the same performance for a different subcarrier (N=64, 128, 256 and 512), Quadrature phase shift keying (QPSK) modulated with OFDM system and AWGN channel, the PAPR-reduction performance shown between PAPR versus CCDF, with used simulation MATLAB R2013a toll .
