Hello,

I am working on designing a digital AGC for a 802.11g modem. This is
my first design that would go on a practical system. I looked for
information on typical AGC designs.. havent been able to find one.

Can you please suggest some good sources for information regarding AGC
control levels, number of samples to use for calculating energy
estimate, reqd PAPR margin and other related issues?

Thanks
