I have been trying to make a baseband transmission by assembling
blocks with GRC.
I’m using this scheme :
To problem is that I’m not able to recover the original data but only
the repetitions of it : I repeat several times two bytes in the input
file and I get several two other bytes at the output.
Any idea to solve this ? Is it possible that the decoding block takes
a bad phase (maybe due to quadrature demodulation)? If so, what block
can I use to make the phase correction ?
