sudo apt-get install cpufrequtils
echo 'GOVERNOR="performance"' | sudo tee /etc/default/cpufrequtils
sudo systemctl disable ondemand

sudo apt update
sudo apt -y install cmake libfftw3-dev libmbedtls-dev libboost-program-options-dev libconfig++-dev libsctp-dev
sudo apt -y install libuhd-dev libuhd003 uhd-host

Sebagai user biasa, jangan sebagai root. Download & compile source code

cd ~
git clone https://github.com/srsLTE/srsLTE.git
cd srsLTE
mkdir build
cd build
cmake ../

make -j8
make test -j8

Pastikan

100% tests passed, 0 tests failed out of 1541

sudo make install
sudo ldconfig

OPTIONAL,

sudo ./srsran_install_configs.sh user

Akan keluar (karena bukan sebagai root)
