[Discuss-gnuradio] Import GNURadio data to matlab. PRIYANKA PRIYADARSHINI Sat, 23 Jun 2018 07:42:46 -0700. Hello Everyone, How can we import the data stored in a file by GNURadio to MATLAB using fread and fseek function??

hackrf_transfer stores samples in 8 bit signed IQ format. It should be straight forward to read them in to Matlab (or GNU Octave). The GNU Radio wiki has a few tips too:

complex float (The file format of this data is .bin i.e binary) In complex float format the data is encoded with 64 bits, 32 bits for I and 32 bits for Q. Example gnuradio block that used codegenerated function from MATLAB. The example is for the estimation of DoA using four input streams with a RootMUSIC algorithm. Generating from MATLAB directly can allow you to easily import complex mathematical functions into gnuradio processing blocks. Since, lets be honest, most of us start in MATLAB anyway.

For more info, see the GNU Radio FAQ entry on the file format. Octave and Matlab Octave is the most popular analysis tool with GNU Radio, as the GNU Radio package includes its own set of scripts for reading and parsing output. Matlab is a closed source tool, and very expensive--but if you already have it installed, you might prefer it to Octave. 1. Create a signal in MATLAB, using the sampling frequency that you will be using in gnuradio. 2. In MATLAB, write the signal to a data file using the m-file: write_float_binary, given below.

Trabajar con GNU Radio o Matlab es una decisión que en general depende de muchos aspectos. Matlab es un lenguaje matemático interpretado que permite de forma sencilla simular sistemas de todo tipo.

Do we expect that the same data recorded in the same format the file size should be the same in both Matlab and GNURadio or GQRX ? Also, whilst recording in pluto I have the option to choose data type as double single or int16.

Since, lets be honest, most of us start in MATLAB anyway. GNURadio documentation says this is a "pure" binary file and consists of 32 bits for the real part followed by 32 for the imaginary (complex float). My intent is to use fread if I can get the file opened. Upon trying to open the file using uiimport MATLAB hangs with "opening a large text file" message and eventually errors with "out of memory". I don't know if there is some compression going on in Matlab but the recorded file does not work in the decoder either.
