Using this method, a reduction of the PAPR of up to 6 dB can be achieved with moderate complexity. Selected mapping (SLM) is a well-known technique for peak to-average-power ratio (PAPR) reduction of orthogonal frequency-division multiplexing (OFDM)...
Yet one of the major drawbacks in OFDM is its high peak-to-average-power ratio (PAPR) of the transmitted signals, which even results in high out-of-band radiation and bit error rate performance degradation. In this paper, various PAPR reduction schemes has been discussed and, also a ...
Orthogonal frequency division multiplexing (OFDM) is a special form of multi-carrier modulation which is robust against the multipath effect, intersymbol interference (ISI) and high spectral efficiency. However, peak to average power ratio (PAPR) is a major drawback in the system since this leads...

A method of reducing peak-to-average power ratio in an OFDM signal comprises the steps of modulating a set of subcarriers with a set of data symbol vectors to produce a first modulated signal, limiting the magnitude of the first modulated signal to produce a first limited modulated signal, ...
However, the great disadvantage of the OFDM technique is its high Peak to Average Power Ratio (PAPR). As we are using the linear power amplifier at the transmitter side so it's operating point will go to the saturation region due to the high PAPR which leads to in-band distortion and ...

Due to the superposition of the individual signal components, the OFDM transmit signal is almost Gaussian distributed and hence exhibits a large peak-to-average power ratio (PAR) [4]. This fact significantly complicates implementation of the r adio frequency (RF) frontend since amplifiers operating...
