Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for broadband wireless transmission due to its robustness against multipath fading. However OFDM signals have a problem with high Peak-to-Average power ratio (PAPR) and thus, a power amplifier must be carefully manufactured to have a linear input-output characteristic or to have a large input power back-off. In this paper, some of the important PAPR reduction techniques have been compared based on computational complexity, bandwidth expansion, spectral spillage and performance.
