Peak to Average Power Ratio sensor for green Cognitive Radio
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010High 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.

On minimizing the peak-to-average power ratio for the sum of N sinusoids
IEEE Transactions on Communications, 1993A new derivation is presented of a previously known relationship for phasing N equal-amplitude, equally spaced (in frequency) sinusoids so that the peak-to-average power ratio of their sum is 2.6 dB. The method of derivation provides intuitive insight into why this result is possible, and shows that the 2.6 dB figure is obtained independently of N as ...

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 ...

Peak-to-Average Power Ratio in WFMT Systems
2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006This paper discuses the peak to average power ratio (PAR) for the signal of a novel wavelet based filtered multi-tone (WFMT) modulation. The wavelet based filtered multi-tone (WFMT) modulation was developed as an alternative line code for xDSL system and represents future extension of OFDM/DMT technologies.
