I want to ask few questions about frequency offset.
1.) Is there have another method except adjusting the coarse and fine word of DCXO to reduce the frequency offset?
2.) What is the function about the both FIR in Tx and Rx signal path? In my opinion it is using for interpolate/decimate of the data, is this FIR can use for reducing the frequency offset?
Please help me to figure out these questions thanks!!
