Hello again,
Sorry, I am not familiar with GNU Radio and I just keep coming up with new
questions...
I am simulating a transmission using IF - Base Band frequency conversion and
a channel_model block introducing noise and frequency offset. As I said I am
particularly interested in the Costas loop performance.
So first of all I would like to make sure frequency_offset parameter really
stands up for a slight deviation between theoretical transmission frequency
and the real frequency at which the signal is sent. What is the unit of this
parameter? Hz?
I would also like to have an idea of the approximative maximum
frequency_offset value that can be corrected by the Costas loop.
I am asking these questions because when looking closely at the Costas loop
NCO frequency value I realized it is far from correcting configured
frequency_offset and this even for small values.
