Peak to Average Power Ratio Reduction in NC–OFDM Systems [PDF]
Journal of Electrical Engineering, 2015 Abstract Non contiguous orthogonal frequency division multiplexing (NC-OFDM) is an efficient and adaptable multicarrier modulation scheme to be used in cognitive radio communications. However like OFDM, NC-OFDM also suffers from the main drawback of high peak to average power ratio (PAPR).

Peak-to-Average Power Ratio analysis in MIMO systems [PDF]
2006 2nd International Conference on Information & Communication Technologies, 2006 In this paper, we analyze the Peak-to-Average Power Ratio (PAPR) in Multiple Input Multiple Output (MIMO) systems based on Alamouti diversity scheme. This analysis is at both transmitter and re- ceiver sides with channel influences. By giving mathematical formulations of the Alamouti scheme signals, we give an upper bound of this signal when Nyquist ...

Peak to Average Power Ratio Analysis for LTE Systems [PDF]
2010 Second International Conference on Communication Software and Networks, 2010 The 3rd generation partnership project (3GPP) long term evolution (LTE) standard uses single carrier frequency division multiple access (SCFDMA) scheme for the uplink transmissions and orthogonal frequency division multiplexing access (OFDMA) in downlink.

Peak-to-Average Power Ratio of Good Codes for Gaussian Channel [PDF]
IEEE Transactions on Information Theory, 2014 Consider a problem of forward error-correction for the additive white Gaussian noise (AWGN) channel. For finite blocklength codes the backoff from the channel capacity is inversely proportional to the square root of the blocklength. In this paper it is shown that codes achieving this tradeoff must necessarily have peak-to-average power ratio (PAPR ...

A Low Complexity Partial Transmit Sequence for Peak to Average Power Ratio Reduction in OFDM Systems [PDF]
Radioengineering, 2011 Partial transmit sequence (PTS) is one of the most important techniques for reducing the peak to average power ratio (PAPR) in OFDM systems. This paper presents a low complexity PTS scheme by applying a new phase sequence.

Peak to Average Power Ratio Based Signal Detection for Frequency Shift Multitone SWIPT System
IEEE Access, 2021 In this paper, we investigate a multitone simultaneous wireless information and power transfer (SWIPT) based modulation scheme for battery-less Internet of Things (IoT) nodes that works in the ultra high frequency (UHF) region.

Generalized Discrete Fourier Transform for FBMC Peak to Average Power Ratio Reduction
IEEE Access, 2019 Filter bank multicarrier (FBMC) is a strong candidate as a waveform based technique in advanced wireless communication systems (e.g. 5G), as an alternative to orthogonal frequency division multiplexing (OFDM). Like all multicarrier modulation techniques,

Time Reduction for SLM OFDM PAPR Based on Adaptive Genetic Algorithm in 5G IoT Networks
Sensors, 2023 In this paper, a new peak average power and time reduction (PAPTR) based on the adaptive genetic algorithm (AGA) strategy is used in order to improve both the time reduction and PAPR value reduction for the SLM OFDM and the conventional genetic algorithm

CLIPPING TECHNIQUES FOR PAPR REDUCTION IN FBMC/OQAM SYSTEM OVER DOUBLY-SELECTIVE CHANNELS
Journal of Engineering and Sustainable Development, 2021 One of the major disadvantages of Filter Bank Multicarrier (FBMC) is high Peak-to-Average Power Ratio (PAPR) of transmitted signal. As a result, nonlinear power amplifier (PA) properties, considerable out-of-band and the in-band distortion types take ...
