hi..
i am working on rx_voice.py for transmission of audio files. In my application,
i need to capture directly the usrp samples and write them onto a file. Now, i
further want do some processing on them using MATLAB. Next, what i want is that
the file be passed to the python code where i can demodulate them as it is done
in receive_path.py . I have been able to capture the data directly from USRP
and write it onto a file by making the connection:
fg.connect(self.u,self.dst)
where self.dst refers to the file. I also do the processing using MATLAB and
again write it onto a different file. Now, the problem is that how should i
pass the new file back to the code so that it gets demodulated. I have tried
running the rx_voice again wherein i make a connection as follows:
fg.connect(self.dst,self.chan_filt,self.packet_receiver)
where self.dst refers to the new file which i want to demodulate.
But, nothing happens on making such a connection. Maybe the problem is because
of the way in which the samples from USRP and files are read. The other option
which i have thought of is to demodulate the entire signal in MATLAB .But tht i
suppose would be pretty tedious because then i will probably have to study all
the C++ implementations of the demod blocks.
Can anyone please suggest any solution. I jus want that the data from a file be
read and demodulated in the same fashion as it is done when it reads direct
samples from the USRP.
Thanks for all the help in advance
