It is not necessary to identify the SDR if only one is connected to the processing board. To enter data from HackRF One or RTL-SDR, use the Osmocom source module in GNU-Radio.
#HACKRF ONE SDR INSTALL#
Sudo apt install lxterminal Osmocom module If you have when launching a model in gnuradio companion a message of the type Xterm executable is missing and if you are on Armbian or Raspbian (raspberry) go to the configuration folder.įirst of all, check that the terminal is installed on your machine. On a terminal in graphics mode type:Ī message “RANDR” missing … is not important. I connect to them by enabling VNC in setup and using the VNC extension in chrome on my PC. Personally, I use my orange-pi or raspberry in remote mode. You have to be in graphics mode to be able to use this superb signal processing design tool. S udo ldconfig Osmocom source module installation DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ONĪt this point I sometimes got an error because the pkg-config package was not found. We clone Osmocom in the user’s Downloads folder for example: Sudo apt-get install cmake build-essential libusb-1.0-0-dev
#HACKRF ONE SDR DRIVERS#
Sudo apt-get install gnuradio Installation Osmocom SDR and RTL-SDR Drivers RTL-SDR and Orange PI One Plus So far for Debian Buster there is only version 3.7.13 which is considered stable.

GNU Radio Companion is a complementary tool allowing to build radio processing chains graphically without writing a line of code. GNU Radio is a very powerful tool for modelling signal processing chains. If the installation is good, you will get a response “Found HackRF” etc … Sometimes with some USB cables that connect the HackRF, there is no response.

HackRF LibraryĬonnect the hackrf to an USB port and check it: Connection of the HackRF One SDR to an Orange Pi Pc2 or Orange PI One Plus running on ARMBIAN or a Radpberry PI. Here we will discuss the connection of these 2 SDRs to an Orange Pi or a Raspberry PI and their operation with the GNU Radio software. RTL-SDR is the cheapest and most well-known SDR working in reception only. eg.HackRF One is an SDR (Software Defined radio) working in transmission and reception in a wide frequency range. Get to number 10, and you will know more about radio signal processing than most engineers.
#HACKRF ONE SDR CODE#
The following challeges are roughly in order of increasing difficultyġ) Add a block code, such as Hamming or BCH.Ģ) Replace the simple AWGN channel model with a Rayleigh or Ricean modelģ) Add a convolutional code (with Viterbi decoder)Ĥ) Implement Orthogonal Frequency Division Multiplexing (OFDM)Ħ) Implement a Low-Density Parity Check code (use the one from the WiFi standard)ħ) Implement a complete 802.11a simulationĩ) Implement a MIMO system, assuming perfect channel knowledgeġ0) Implement a MIMO system with channel estimation Once you have the BPSK simulation, try extending your simulation in different directions and matching the textbook curves. A BPSK should be quite doable for an amateur. If you can get the waterfall curve to match exactly, you will also be covering concepts such as "energy per bit". By doing this, you will learn about modulation, demodulation and and "Additive White Gaussian Noise" (AWGN) channel models. Don't stop until you can get your curve to perfectly match the one in a text book. If you're seriously interested, download Octave (Matlab replacement) and write a program from scratch to simulate a BPSK system and generate a "waterfall" (bit error vs. You don't even need hardware to start with.
