scaling question for PAPR in OFDM

Started by cool...@hotmail.com September 8, 2006
I have a simple question about calculating the PAPR in matlab. I am doing an OFDM simulation where I have say N data points and then I do the IFFT on these N data points with 4 times oversampling. Now when I calculate the Peak to Average Power Ratio I get a very small number so what I'm trying to figure out is what number I should multiply it by to get it scaled correctly. Is it 4*N? or am I missing something. Thanks in advance
