Coding Schemes Applied to Peak-to-Average Power Ratio (PAPR) Reduction in OFDM Systems
2008 International Wireless Communications and Mobile Computing Conference, 2008High PAPR of the transmitted signal is a major drawback in the OFDM systems. In this paper, coding schemes are proposed to reduce high PAPR One is using parity check coding scheme, and the other is using selected mapping (SLM) applied scheme. With parity check coding scheme, the parity information is used to expand the signal space.

Peak-to-Average Power Ratio (PAPR) Reduction by Pulse Shaping Using the K-Exponential Filter
IEICE Transactions on Communications, 2010A K-exponential filter is derived and utilized for pulse shaping to reduce peak to average power ratio (PAPR) without intersymbol interference (ISI). While keeping the same bandwidth, the frequency responses of the filters vary with different values of the parameter k.

Performance Analysis of Peak-to-Average Power Ratio (PAPR) Reduction Techniques in an OFDM System
2012 Third International Conference on Computer and Communication Technology, 2012Orthogonal Frequency Division Multiplexing (OFDM) has been currently under intense research for wireless transmission due to its robustness against multipath fading. However, it has some limitations such as the Peak-to-average power ratio (PAPR), which restricts its use. It reduces the efficiency of the system.

Partially clipping (PC) method for the peak-to-average power ratio (PAPR) reduction in OFDM
2004 IEEE 15th International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE Cat. No.04TH8754), 2005OFDM (orthogonal frequency division multiplexing) has emerged as one of the best modulations for broadband mobile communications. Despite its robustness against multipath interference, the drawback of peak-to-average power ratio (PAPR) has to be overcome.

Peak to Average Power Ratio (PAPR) reduction in OFDM for a WLAN network using SLM technique
2011 3rd International Conference on Electronics Computer Technology, 2011Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. OFDM modulation schemes offer many advantages for multicarrier transmission at high data rates over time dispersive channels, particularly in mobile applications.

Peak-to-Average Power Ratio of OTFS Modulation
IEEE Communications Letters, 2019In this letter, we analyze the peak-to-average power ratio (PAPR) of orthogonal time frequency space modulation (OTFS) waveform. Towards this, we consider modulation symbols on an $N\times M$ delay-Doppler grid, where $N$ and $M$ are the number of ...
