Hi Hais, > kindly guide me how can i save the received signal in GNU radio software Have you gone through the tutorials on http://tutorials.gnuradio.org ? Like I said, use the "file sink". It's really not that hard if you just get started with these tutorials! > what should be the format of received signal file so that it can be > imported in matlab for signal analysis..?? That one is asked quite frequently; here's the answer: To cite [1]:
> All files are in pure binary format. Just bits. That’s it. A floating > point data stream is saved as 32 bits in the file, one after the > other. A complex signal has 32 bits for the real part and 32 bits for > the imaginary part. Reading back a complex number means reading in 32 > bits, saving that to the real part of a complex data structure, and > then reading in the next 32 bits as the imaginary part of the data > structure. And just keep reading the data. > > Take a look at the Octave and Python files in gr-utils for reading in > data using Octave and Python’s Scipy module. > So, just go ahead and look at the read_something.m files in [2]. they contain matlab code.
