some questions about "phase_offset" in module sync_short

[wwy9931154]

hello sir, thank you for your amazing work.I would like to ask you some tips about the module “sync_short”. There is a output named “phase_offset”,Is this the frequency offset you calculated using a short training sequence(coarse estimation)? I read the comment and found that it seems to be approximated as an integer, what is its range? If I can understand this information, it will definitely be very helpful for my learning. Looking forward to your reply!
