hello guys,
thank you Josh, Achilleas and Eric for the very precious help! :)

I've been working upon your suggestions and what I did is:


file_chunker=gr.packed_to_unpacked_bb(2,1) #second argument is
endianness (??)

print constellation
symbol_mapper=gr.chunks_to_symbols_bc(constellation, 1)



which connected to an inverse fft and then sent out brings out the
attacched screenshot.

is the constellation mapping well done? (in terms of block usage I mean)

thanks for help and attention


I'm trying to move as close as possible to ofdm with qpsk mapping on the
python level..
