Abstract
Multicarrier technique orthogonal frequency division multiplexing (OFDM) modulation
is a solution to provide high-speed and secured data transmission requirement in
4G technologies. Peak-to-average power ratio (PAPR) is one major drawback in OFDM
system. Researches described several PAPR reduction techniques, notably peak windowing
and clipping. The aim of this paper is to use these techniques to reduce PAPR.
The research work describes clipping and windowing techniques such as quadratic
amplitude modulation (QAM) and additive white Gaussian noise (AWGN) as channel
condition. The simulation results show that in those techniques with clipping threshold
level of 0.7, there is a reduction of PAPR of 8 dB, and the reduction of PAPR for the peak
windowing when considering Kaiser window is about 11 dB.
