Hello,
I would like to implement the process as follows at the Rx side: Record
the time when the first sample arrived, and then wait for a certain
interval and then send ack back to Tx. Meanwhile, finish the cfo
calculating and compensating.
Here is my whole flow graph design. (Each means a block)
pkt_dtc-> cfo_calc -> file_sink
cfo_calc -> cfo_cpst
file_source -> cfo_cpst -> usrp_sink
where pkt_dtc, grab_time_tag and cfo_calc was done myself with C++.
However, My question are:
1. Is it correct of my whole desgin (I want to implement them in one top
block) or are there any easier solutions ?
2. After the block grab_time_tag, how should I pass the time information
(directly got from the method get_tags_in_range) into the usrp_sink as a
parameter so as to send ack at the intended time? Should I write in
Python(but they are not the same level) or C++(but I can't rewrite a
usrp_sink) ?
Any doubts or suggestions are highly appreciated !
