Constellation Decoder problem in GRC

Hi,
I am working in GRC and I am Designing My own 16 QAM Transceiver
without
using the QAM modulation and demodulation blocks of GRC. I have done
modulation using the python function qam_constellation from source code
but
now I have a problem how to demodulate the 16QAM without using the QAM
demodulation block of grc while I am working in GRC window.
My grc code is attached to this message below.

Try using the Constellation Receiver instead of the Constellation
Decoder. The Receiver implements phase and fine frequency tracking
that you’ll need to recover the signal. The Decoder simply decodes the
symbols to bits.
