Re: [Discuss-gnuradio] how to see the captured dat file in octave or any other software

[Thomas Hobiger]

Hi,

Getting the data into Octave is quite easy

fid=fopen('file.dat');
readsize=1000; % e.g. if you want to read 1000 samples
ir=1:2:2*readsize-1;
ii=2:2:2*readsize;
[val, count] = fread (fid, readsize*2, 'float'); % times 2 for reading I/Q data
s=complex(val(ir),-val(ii));  % put the data into a complex vector
%
% ... some processing here
%
fclose(fid);


Regards,
  Thomas

Hi,

I am new to gnu radio and I have a dat file (complex or float) captured from file sink which was directly connected USRP.

Can anyone help me with how to see the dat file in octave or any other similar software. Is there any other method to see the content of dat file as i need that data for processing.

Thanks and Regards,
Abhijeet.
