Symbol Sync Block Python Source File Passing Wrong Constellation

[Ceren Karaköse]

Hi all,

I'm using Symbol Sync from core GNU library. Although when Gardner TED is selected, the parameters section **do not**have any option to define a slicer constellation, the generated python file passes qpsk.base as slicer argument as follows:

        self.digital_symbol_sync_xx_0_0_0 = digital.symbol_sync_cc(

            digital.TED_GARDNER,

            xsample,

            my_loopbw,

            my_damp_fac,

            my_ted,

            my_maxdev,

            1,

            digital.constellation_qpsk().base(),

            digital.IR_PFB_MF,

            nfilts,

            rrc_taps)

I would like to modify the default qpsk.base constellation as I'm using a different one. My question is can I do so without messing with the generated .py file? I would much prefer passing the argument using GNU interface instead of manually modifying .py file.

Thanks a lot,
Best regards,
Ceren
