Help: Constellation Receiver::Object

GNU Radio
1

I am trying to use the Constellation Receiver Block and one of the
Parameters is “Constellation Object”. Is this a pointer to an object and
how/what creates this object? I have looked at the qam.py file but don’t
follow how this relates to placing a block down in gnuradio companion.
Thanks…Tom

Tom,

I am trying to use the Constellation Receiver Block and one of the
Parameters is “Constellation Object”. Is this a pointer to an object and
how/what creates this object? I have looked at the qam.py file but don’t
follow how this relates to placing a block down in gnuradio >>companion.
In GRC u can use

  1. from gnuradio import digital (Using Import block)
  2. my_const_obj = digital.constellation_qpsk() (Using variable
    block).
    To see other options for creating the constellation object see

http://gnuradio.org/doc/doxygen/classgr_1_1digital_1_1constellation.html
3) In constellation receiver>constellation Object parameter add
my_const_obj.base()
