Abstract

Orthogonal Frequency Division Multiplexing or OFDM is a form of multi-carrier modulation technique. High spectral efficiency, robustness to channel fading, immunity to impulse interference, uniform average spectral density, capability of handling very strong echoes and less nonlinear distortion are among the favorite properties of OFDM. Even though there are many advantages of OFDM, it has two main drawbacks, high Peak to Average Power Ratio (PAPR) and frequency offset. Clipping, companding, partial transmit signaling (PTS), selected mapping (SLM), interleaving, coding etc. are various PAPR reduction techniques. In this paper, the simulation results of PAPR without any reduction technique, with clipping technique and with companding technique are evaluated.
