Peak-to-Average Power Ratio Reduction in MIMO OFDM

2007 IEEE International Conference on Communications, 2007
Peak-to-average power ratio (PAR) reduction in OFDM using antenna arrays (MIMO OFDM) is considered. In particular, generalizations of selected mapping (SLM) recently proposed in literature, are studied, and a new version, we call it directed SLM (dSLM), is introduced.

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.

On minimizing the peak-to-average power ratio for the sum of N sinusoids

IEEE Transactions on Communications, 1993
A 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 ...

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 ...
