Hi Martin, I am thinking of doing equalization and estimation in a single python code. For this i think, i may need to translate *ofdm_frame_equalizer_vcvc *block also in Python. But it would also be nice if i can use ofdm_frame_equalizer_vcvc block in conjunction with the Python-based equalizer. For now i am stuck at how to write *d_constellation->map_to_points(d_constellation->decision_maker(&sym_eq),** &sym_est); *in a python code for equalizer.
Thanks.
