基于OpenLTE的4G移动通信网络实验指导书

基于本人本科毕业设计的成果，设计了一套基于开源SDR项目——OpenLTE的实验指导书，可以指引读者通过平台源码、平台提供的实验和结合实验对3GPP规范的解读分析来更直观、更多元立体的学习无线通信技术，而不是纯粹的理论学习或只是进行观摩性质的演示实验。

1 OpenLTE平台搭建

本小节内容为OpenLTE移动通信实验平台的搭建过程，是后续实验环节的环境基。此处将详细介绍经过多次测试后可较稳定运行环境版本的安装过程。全部环境建立在实体系统的Ubuntu16.04或18.04上，进行安装前请先确认非虚拟机的系统安装完毕。如在虚拟机中运行平台将无法保证USRP与计算机的稳定连接，也无法保证平台的正常运行。

在调试过程中可能需要卸载某些插件，卸载方式均为在编译文件夹中运行：

sudo make uninstall

1.1 UHD安装

1）在安装UHD前，需先安装所需依赖项。

在终端中运行：

sudo apt-get update

若是Ubuntu 18.04系统，运行：

sudo apt-get -y install git swig cmake doxygen build-essential libboost-all-dev libtool libusb-1.0-0 libusb-1.0-0-dev libudev-dev libncurses5-dev libfftw3-bin libfftw3-dev libfftw3-doc libcppunit-1.14 -0 libcppunit-dev libcppunit-doc ncurses-bin cpufrequtils python-numpy python-numpy-doc python-numpy-dbg python-scipy python-docutils qt4-bin-dbg qt4-default qt4-doc libqt4-dev libqt4-dev-bin python-qt4 python -qt4-dbg python -qt4-dev python -qt4-doc python -qt4-doc libqwt6abi1 libfftw3-bin libfftw3-dev libfftw3-doc ncurses-bin libncurses5 libncurses5-dev libncurses5-dbg libfontconfig1-dev libxrender-dev libpulse -dev swig g ++ automake autoconf libtool python-dev libfftw3-dev libcppunit-dev libboost-all-dev libusb-dev libusb-1.0-0-dev fort77 libsdl1.2-dev python-wxgtk3。0 git libqt4-dev python-numpy ccache python-opengl libgsl-dev python-cheetah python-mako python-lxml doxygen qt4-default qt4-dev-tools libusb-1.0-0-dev libqwtplot3d-qt5-dev pyqt4-dev-tools python-qwt5-qt4 cmake git wget libxi-dev gtk2-engines-pixbuf r-base-dev python-tk liborc-0.4-0 liborc-0.4-dev libasound2-dev python-gtk2 libzmq3-dev libzmq5 python-requests python-sphinx libcomedi-dev python-zmq libqwt-dev libqwt6abi1 python-six libgps-dev libgps23 gpsd gpsd-clients python-gps python-setuptools4-dev libasound2-dev python-gtk2 libzmq3-dev libzmq5 python-requests python-sphinx libcomedi-dev python-zmq libqwt-dev libqwt6abi1 python-six libgps-dev libgps23 gpsd gpsd-clients python-gps python-setuptools4-dev libasound2-dev python-gtk2 libzmq3-dev libzmq5 python-requests python-sphinx libcomedi-dev python-zmq libqwt-dev libqwt6abi1 python-six libgps-dev libgps23 gpsd gpsd-clients python-gps python-setuptools

             若是Ubuntu 16.04系统，运行：

2）从源代码构建和安装UHD。

克隆源文件到本地，并进入文件目录：
git clone https://github.com/EttusResearch/uhd
cd uhd
