HackRF One—安装srsRAN并测试
前言
rsrRAN是支持"UHD", "bladeRF", "soapy", "zmq" ,"Sidekiq"的，如果使用的USRP设备，则会用UHD，HackRF的话，则需要先安装soapy，之后srsRAN才能够调用。因此本博客主要分为了四个内容1.安装SoapySDR；2.安装Soapy HackRF；3. 安装srsRAN；4.测试示例。
1 安装SoapySDR
可以参考其官方的wiki：https://github.com/pothosware/SoapySDR/wiki/BuildGuide#ubuntu，安装步骤如下：
1、获取依赖项
sudo apt-get install cmake g++ libpython3-dev python3-numpy swig
2、获取源码
git clone https://github.com/pothosware/SoapySDR.git3、编译并安装
mkdir build
cd build
cmake ..
make -j4
sudo make install4、查看SoapySDRUtil信息
cd apps
./SoapySDRUtil --info

如果要使用HackRF One的话，必须要安装完前两步，如果不幸先编译安装了srsRAN，会提示找不到设备，就算调成了soapy。需要重新编译安装。而如果你想要使用srsGUI看到图像化界面的话，也需要先安装srsGUI，再安装srsRAN，具体方法如下。
3.1 安装srsGUI
如果不先安装srsGUI，直接安装srsRAN，是无法显示界面的，必须先安装srsGUI，在安装srsRAN才能正确显示界面。
1、安装依赖项
sudo apt-get install libboost-system-dev libboost-test-dev libboost-thread-dev libqwt-qt5-dev qtbase5-dev2、获取源码
git clone https://github.com/srsLTE/srsGUI.git3、编译安装
cd srsgui
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig3.2 安装srsRAN
1、安装依赖项
sudo apt-get install cmake libfftw3-dev libmbedtls-dev libboost-program-options-dev libboost-thread-dev libconfig++-dev libsctp-dev
2、获取源码
git clone https://github.com/srsran/srsRAN.git3、编译安装
mkdir build
cd build
cmake ../
make
make test
sudo make install
sudo ldconfig 4、若报错出现无mbedtls包，No package 'mbedtls' found，则安装即可
mbedtls安装与入门【转】 - sky-heaven - 博客园
git clone https://github.com/ARMmbed/mbedtls.git# 更新软件源
sudo apt-get update
# 通过软件源安装cmake
sudo apt-get install cmake
# 生成makefile文件，启用生成动态链接库选项
cmake -DUSE_SHARED_MBEDTLS_LIBRARY=On
# 以下步骤和make方式相同
make SHARED=1
sudo make install5、若报错ModuleNotFoundError: No module named 'jinja2'，则安装python-jinja2:
pip3 install jinja2不再出现错误，成功安装就可以开始使用了。
4 测试用例
对srsRAN进行简单的测试，具体使用文档大家可以看官方提供的PDF文档。https://docs.srsran.com/_/downloads/en/next/pdf/
4.1 srsEPC,srsENB,srsUE
完全安装好了srsRAN，我们先测试一下使用srsepc，srsenb，srsue看能不能实现，其中srsepc和srsenb可以运行在一台电脑和RF设备上，srsue需要运行在另一台电脑并使用另一个RF设备。因为我只有一个HackRF One，所以仅进行了运行测试，发现没问题。
（1）调用srsepc

4.2 NB-IoT测试
我们使用./srsRAN/build/lib/examples提供的示例来基站扫描和解码。
1、扫描，国内的NB-IoT主要运行在B5和B8频段，所以我们扫描b 8或b 5，当然我们也可以使用自己的手机调到3G/2G网络，来看基站频率。
sudo ./cell_search_nbiot -b 8Found XX cells
Found CELL XXX MHz, EARFCN=XXX, PHYID=XXX, NPSS power=17.1 dBm
Found CELL XXX MHz, EARFCN=XXX, PHYID=XXX, NPSS power=-11.5 dBm
Found CELL XXX MHz, EARFCN=XXX, PHYID=XXX, NPSS power=-11.5 dBm
Bye
2、选取一个小区，进行解码，如果信号较弱，可以添加-g 40 参数来提高增益。
sudo ./npdsch_ue -f 949.2e6
4.3 LTE测试
LTE和NB-IoT类似，在example文件中，存在cell_search和pdsch_ue，使用方法也是类似的，这里不再赘述。示例如图。 LTE运行在B3，B40，B41频段等，可以自行查新
sudo ./cell_search -b 40sudo ./npdsch_ue -f 1835.6e6 -g 40
