Hello Jahnavendra Mattipa:
Unfortunately, I am having a trouble opening your GRC file. If you are
reading it from GNU Radio, you can simply use a file source. If you are
using Matlab/Octave, you can do something like this:
read = fread(fopen('sam.dat'),2048,'single');
IQ = read(1:2:end) + read(2:2:end)*i;
Where 'sam.dat' is the file path, 2048 is the length to read, and 'single'
is the datatype (ieee754 single precssion). (Assuming complex datatype; if
float, data is not interleaved so you should skip the second line).
The data is in pure binary format, so text editors won't open it properly
(as explained in the GNURadio wiki).
Regards,
Kyeong Su Shin
