power amlifier
hi guys,
i need ur idea again.
we identify OBO with this formula OBO = log(Pout/Pin) right?
in many tutorials such as Shinsuke Hara and Ramjee Prasad titled Multicarrier Techniques for 4G Mobile Communications, published 2003 (p.85) there is a graph illustrates power spectrum of OFDM on OBO (-5 dB), that is x and y axises define bandwidth and psd (power spectral density) properly.
My question is where is the connection of OBO with psd, i mean can somebody give me mathematical formulas of their relationship?
thanks a lot!
