Hi all,
Have you heard about Modulation Compension Circuit (MCC)? In traditional wireless application because of use PLL (phase locked loop), when there is a long string of zero or one in NRZ application, it likes a very low frequency and this kind of low frequency cannot be modulated in PLL because PLL is a high-pass in nature with signal below loop bandwidth cannot be modified. So two kind of method, one is open-loop modulation and another two-point modulation.
But some chips use close-loop with employ MCC technique, any idea?
Thanks in advance!
