[@shayg2956]

Love your lectures, all of them. Thank you from Israel.

[@gototcm]

Please write a book. Your teaching skills are exceptional.

how PAPR occurs

[@09372556612]

Great presentation !

[@rajatchauhan9236]

please upload lecture on partial transmit sequence for papr reduction in ofdm, and lectures on Wavelet packet ofdm

[@이혜인-d8f]

Thank you so much

[@ahmedanwar7316]

Great Presentation :)

[@bommidisridhar]

nice lecture. Can we use wavelets instead of get here?

how IFFT produces PAPR

[@rohitkashyap4304]

One way to view the output of the IFFT block is that each pin it's a weighted combination of N independent modulated symbols. A fair assumption is that they have finite second order moments. Which implies that the sum almost surely converges to a Normal distribution with certain variance. This is problematic as there is a non zero chance that the IFFT samples might exceed the linear range of a power amplifier and cause spectrum spreading leading to high PAPR.

Hello I want help from you to do an investigation with an easy good subject if you could. I didn't find your email address.
