Hi Frank, For the same reason, constellation_16qam is not in the current constellation module yet. Unlike 8psk_natural which you have a replacement constellation_8psk, no 16-ary constellation is available in current constellation module.
You can try to modify the cdma_parameter.py by deleting the tcm type 16qam+rate 2/4 convolutional code. Just delete digital.constellation_16qam() in payload_mod, pdir+ awgn2o4_8_ungerboeckc.fsm in fsm, and trellis.fsm(4,4, blabla...) in uncoded_fsm. If I missed anything, please be careful to delete anything related to 16qam and 2/4 cc code. It would be easy. You should be able to run it with two tcm types.
