RE: [Discuss-gnuradio] Question regarding matched filter outputs

[Dumezie Maduike]

I'm sorry if I wasn't clear in my question.  After a packet is transmitted
from one USRP to the next using BPSK, the analog signal that gets to the
receiving USRP, it needs to be converted to binary 1's and 0's based on a
threshold which is usually 0V in BPSK.  I wanted to know which file (either
.py or .cpp) handles that received analog signal before it is converted to
binary 1's and 0's.  I tried to trace it from benchmark_tx.py to
benchmark_rx.py and I wasn't able to locate it.

I hope this clarifies it.

Thanks in advance

Dumezie

I don't understand the question.  Are you just referring to the output
of a, lets say, RRC filter before transmission?  If so, you can tap
off at any point in the signal chain.  If not - can you be more clear
with your question?
