USRP driver and dependency installation

---

Installation on Ubuntu 22.04

---

Install UHD and GNU Radio and all needed dependencies:

---

UHD installation

UHD installation from source code is required

See https://files.ettus.com/manual/page_build_guide.html

Alternatively, first install the following dependencies

CMAKE:  http://www.cmake.org/cmake/resources/software.html

BOOST:  http://www.boost.org/users/download/

LibUSB:  http://sourceforge.net/projects/libusb/files/libusb-1.0/

Python: http://www.python.org/download/

Mako: http://www.makotemplates.org/download.html

Doxygen: http://www.doxygen.nl/download.html

You can setup all above by using

sudo apt-get install autoconf automake build-essential ccache cmake cpufrequtils doxygen ethtool \
g++ git inetutils-tools libboost-all-dev libncurses5 libncurses5-dev libusb-1.0-0 libusb-1.0-0-dev \
libusb-dev python3-dev python3-mako python3-numpy python3-requests python3-scipy python3-setuptools \
python3-ruamel.yaml 

then download and isntall UHD:

git clone --branch UHD-4.0 https://github.com/ettusresearch/uhd.git uhd

cd /uhd/host/
mkdir build
cd build
cmake ..
make
make test
sudo make install
sudo ldconfig

Set variable environment

export LD_LIBRARY_PATH=/usr/local/lib
export UHD_IMAGES_DIR=/usr/local/share/uhd/images

and run

uhd_find_devices

You also need to run

sudo uhd_images_downloader

Finally, you need to locate and add libuhd.a or libuhd.so to your project

Further, to take FFT, we need to a library that I would recommend FFTW, which can be installed in Ubuntu by (see a tutorial here ! )

sudo apt-get install libfftw3-dev

Or alternatively install it from source code, by downloading it from here

http://www.fftw.org/download.html

then

tar -xvf fftw-3.3.10.tar.gz
cd fftw-3.3.10
./configure
make
sudo make install

the libfftw3.a will be installed in

usr/local/lib/

Finally, it should be added to the project as a library, as the standard procedure for using libraries.

GNU Radio Installation

For our applications, we just need binary installation of GNU Radio

sudo apt update
sudo apt install gnuradio-dev gr-osmosdr cmake libsndfile1-dev

Now, we need to also run images_downloader in

/usr/lib/x86_64-linux-gnu/uhd/utils/uhd_images_downloader.py

You might have to disconnect and re-connect your SDR if it was already connected to your computer.

Optimize VOLK

GNU Radio use VOLK to do most of the computations. To allow VOLK to chose the best implementations of its DSP algorithms you should run

volk_profile
