Optimized Peak to Average Power Ratio (PAPR) Reduction Technique for OFDM
2017 International Conference on Computing, Communication, Control and Automation (ICCUBEA), 2017Orthogonal Frequency Division Multiplexing (OFDM) is one of the widely used multicarrier technique for high speed data transmission. One of the main drawbacks of OFDM is the high Peak to Average Power Ratio (PAPR). It is the ratio of maximum power of the signal to its average power. Many techniques have been developed to lower the values of PAPR. Among

Comparative analysis of peak-to-average power ratio (PAPR) reduction techniques for OFDM system
2013 4th International Conference on Computer and Communication Technology (ICCCT), 2013Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high-speed data transmission over multipath fading channels. 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.

Peak-to-Average-Power-Ratio (PAPR) Reduction Methods with Wavelet Transform in MIMO-OFDM
IETE Journal of Research, 2017ABSTRACTThis study is based on the comparison of the results with an analysis method recommended for the Peak-to-Average-Power-Ratio (PAPR) reduction methods. This is one of the most significant problems in the Multiple Input–Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems.

Peak-to-average power ratio (PAPR), fractional bandwidth and processing gain of UWB schemes
Eighth IEEE International Symposium on Spread Spectrum Techniques and Applications - Programme and Book of Abstracts (IEEE Cat. No.04TH8738), 2005This paper addresses the peak-to-average power ratio (PAPR), fractional bandwidth and processing gain of ultra-wideband (UWB) signals. First, the PAPR of UWB signals are derived and the numerical examples demonstrating PAPR values with Gaussian monocycle pulse shaping are presented.

Reducing peak-to-average power ratio (PAPR) using partial transmit sequence in OFDM systems
7th International Multi Topic Conference, 2003. INMIC 2003., 2005OFDM is a multicarrier system supporting high data rate transmission and generally requires no equalization at the receiver, making it simple and efficient. However, a drawback of this system is the large peak-to-average-power ratio (PAPR) of the transmit signal, which makes its straightforward implementation quite costly.
