OFDM average power

P.S. In real circuits, power factor (the cosine of the angle between
voltage and current) matters. As PF goes to zero, PAR goes to infinity.

I think you are thinking about PF issues with power supplies with small
conduction angles and non sinusoidal current waveforms due to cap input
filters.... ,  the traditional PF caused by sinusoidal current and
voltage out of phase does not impact PAR.

Oh? How do you define peak-to-average power ratio? I think it's (peak power)/(average power). When PF is zero, so is average power. It is zero because the positive power and negative power cancel. I'll show more analysis if you ask for it. Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������
