MAC implmentation with dbpsk

GNU Radio
1

Hey ,
I am trying to configure a MAC layer implementation ( a customised
packet structure ) abiding by the basics of benchmark files. ( The basic
msg_source(packet input) --> modulator --> multiply_const --> sink) on
the
TX side and pretty much reverse on the receiver side .
My question to you is

  1. With the most recent version of gnuradio the dbpsk file was removed
    and
    in place a dbpsk_mod was placed in bpsk.py which pretty much takes care
    of
    symbols to constellations, how credible would this method be in place of
    the old dbpsk.py that had the bytes2chunks --> symbol_mapper -->diffenc
    –>rrc ?

Thanks,
Josh.
