Peak to average ratio

Webtransmit signal PAPR (Peak-to Average Power Ratio) to size the back-off value of the power amplifier, little attention has been paid to it. In this paper the key aspect is the PAPR, which is fundamental to face transmitter designs optimizing the trade-off between linearity and the time-of-life of the batteries. The peak-to-average power ratio ( PAPR) is the peak amplitude squared (giving the peak power) divided by the RMS value squared (giving the average power ). [1] It is the square of the crest factor. When expressed in decibels, crest factor and PAPR are equivalent, due to the way decibels are calculated for power … See more Crest factor is a parameter of a waveform, such as alternating current or sound, showing the ratio of peak values to the effective value.
