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:

который дает вам двоичные файлы float 32. Или просто используйте скрипты octave/Matlab в GNU Radio , которые делают именно это: пишут

Matlab gnuradio

Below I show how to command MATLAB to compute and display the spectrogram of y. Here the signal is divided into sections of length 200000, with 1500 samples of overlap between adjoining sections. The frequency axis is set between -1.25 MHz and +1.25 MHz (principle frequency axis). Hi list, I'm writing a program to use QAM using a combination of Matlab and gnuradio (QAM demod hasn't been implemented in gnuradio).

Hello I am doing a project using ADI's famcomms5, so I transmitted and received a file which I then saved into a binary file using GNU Radio 's file sink. Now this is a binary file, if I open this file in GNU Radio I can see the different wave responses but when I import the file into matlab it shows scrambled symbolic data which I am not able to read or work on further.

In my previous post under the label MATLAB GNURadio I told about How to move data between GNU Radio and MATLAB using Octave. Today I will tell the same without using Octave.bin to .mat Say you have collected complex data using uhd_rx_cfile and saved it in a file say my_data and number of samples you collected is 'N' Now open MATLAB : 1. I have a 1.5GB binary file that was created via recording in GNURadio with an SDR. 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).

S.h. plattner et al., simple signal processing of linear voltammetric data with matlab: interpolation function for simple signal processing of linear voltammetric data

GNU Radio has a built-in functionality with stream tags to keep track of timing information. This can be useful for working with packetized data, but currently there isn’t any way to save those tags along with data to look at later. I’ve been working on a few blocks that might be able to help with this.

Mathys Lab 3: Introduction to Software De ned Radio and GNU Radio 1 Introduction A software de ned radio (SDR) is a \Radio in which some or all of the physical layer I modelised this on Matlab (for BPSK but that is the same problem) and here is a plot of the signal at the reception after matched filtering : The FIR used here is a Root Raised Cosine. The thing is that the polyphase clock sync will find the minimum derivative of this signal to know where to downsample but this is for me not the right location. A comm.SDRRTLReceiver System object™ supports communication between MATLAB ® and an RTL-SDR device, allowing simulation and development of various software-defined radio (SDR) applications.

suggest to take a page from Bill Gates: add low-level compatibility for "other" RF software to GNU Radio software (typical examples such as transfer data, call MATLAB functions, MATLAB-callable functions), and eventually the "others" will discover how much better, well-supported, and dynamically growing is your GNU Radio software.

How to get the data collected from GNU Radio to MATLAB and vice versa From GNU Radio to MATLAB : 1. Suppose you collected data using uhd_rx_cfile and the wire format is fc32 i.e. 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.
