Hello Sabbir

I think that has to work according to formula,it seems correct..
Did you run this program?
Let me know..
and would you be able to tell me how do we apply this concept for OFDM?
I am working on reducing PAPR in OFDM and went through the concepts and methodologies,still i am not sure how exactly to get the power values of carriers in OFDM and find PAPR.
Please help me..
AND request to all others,please suggest..
