Re: carrier recovery

Hi,

Are you able to acquire the signal with the modulation?
What is happening to the carrier during acquisition.

Re: carrier recovery

yes signal is received but problem is when we give it a frequency offset of 1khz, eye diagram shows too much of noise so we have to use a pll but dont know how
