Peak-to-average power ratio reduction of FDRM

2005 International Symposium on Intelligent Signal Processing and Communication Systems, 2005
Frequency Domain Reciprocal Modulation (FDRM), originally developed by T. D. Williams [1, 2], is an enhanced method of modulation to complement Orthogonal Frequency Division Multiplexing (OFDM) techniques. FORM was proposed to solve the problem of very fast dynamic multipath distortion in wireless communication environments.

Peak-to-Average Power Ratio of OTFS Modulation

IEEE Communications Letters, 2019
In 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 Doppler and delay bins, respectively.

Peak to Average Power Ratio sensor for green Cognitive Radio

21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010
High Peak to Average Power Ratio (PAPR) is a critical issue in multi-standard and multi-carrier communication systems. This problem can result in large performance degradation due to the non-linearity of the High Power Amplifier (HPA) or in low power efficiency.

Calculation of peak-to-average power ratio in DVB-T

47th International Symposium ELMAR, 2005., 2005
Extremely high peak power values are the major problem in digital terrestrial television (DVB-T). They are caused by multi-carrier modulation COFDM (Coded Orthogonal Frequency Division Multiplex). This paper contains analysis of this problem from the aspect of theoretical peak power maximum and statistical analysis of the problem where DVB-T parameters

A Gradient Based Peak-to-Average Power Ratio Reduction Method

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
One promising approach to peak to average power ratio (PAPR) reduction for orthogonal frequency division multiple access (OFDMA) is the use of reserved tones, which are modulated so as to reduce the PAPR. One problem with this approach is the computationally efficient determination of reserved tone signals that best reduce the PAPR.

On the links between peak to average power ratio for conventional RF power amplifiers and peak to average duration ratio for switching mode power amplifiers

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
For conventional RF power amplifier (PA), the power efficiency depends on the peak to average power ratio (PAPR) of the input signal, or more precisely on the statistical distribution of the input signal amplitude. In this paper we show that, in a similar way, the power efficiency of switching mode PA driven by ΣΔ or PWM signals depends on the ...

DMT signals with low peak-to-average power ratio

Proceedings IEEE International Symposium on Computers and Communications (Cat. No.PR00250), 2003
This contribution proposes a new family of methods to reduce the peak-to-average power ratio (PAR) in discrete multi-tone (DMT) and orthogonal frequency division multiplexing (OFDM) systems. This method avoids the use of extra inverse fast Fourier transformations (IFFT) as were used in some previously published techniques, but instead is based on ...

On minimum peak-to-average power ratio spectral factorization

2011 8th International Workshop on Multi-Carrier Systems & Solutions, 2011
The design of a filter with a given autocorrelation function — or in other words, the factorization of an autocorrelation sequence — is a standard task in digital communications. This paper demonstrates that different spectral factors have a different impact on finite-support random sequences in terms of peak-to-average power ratio.

Peak to average power ratio reduction of OFDM system

International Conference on Information Communication and Embedded Systems (ICICES2014), 2014
Orthogonal frequency division multiplexing (OFDM) is a modulation technique that is suitable for high data rate communication. But the main drawback of OFDM is its high peak to average power ratio (PAPR), which can lead to nonlinear distortions in the power amplifiers at the transmitter side.
