Abstract

The high peak-to-average power ratio (PAPR) of the transmitted signal in Orthogonal Frequency Division Multiplexing (OFDM) system. It leads to problems as which distorts the signal if the transmitter contains nonlinear components such as power amplifiers and causes some deficiencies such as inter-modulation, spectral spreading and changing in signal constellation. The favorite properties of OFDM signal is it has 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. Even though here are many advantages of OFDM, it has two main drawbacks, they are high PAPR and frequency offset. The result of the PAPR effect in OFDM system is investigated and proposed a novel approach to reduce PAPR effect using selective mapping (SLM) technique.
