If I am correct, it should be in the file dbpsk.py, and the module is Self.slicer = gr.constellation_decoder_cb(retated_const, range(arity))

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.

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?
