I understand the intuitive way in which first the phase offset is found.
from that you can find finefrequency offset and timing offset. But I am
looking at how all this is done in the code using appropriate equations,
especially how coarse frequency offset is found using the math. The
paper
says there will be a factor of 2z/T that you should consider when the
offset is greater than half the subcarrier spacing. i.e. integer
frequency
offset. Hopefully a page on how the sync is being implemented in the
code
would help. I have to blame my poor c++ skills for all this pain.
