0x00 概览
LimeSDR部分特性：
USB 3.0 ；
4 x Tx 发射天线接口 6 x Rx 接收天线接口；
可用于Wi-Fi, GSM, UMTS, LTE, LoRa, Bluetooth, Zigbee, RFID等开发测试环境中。
RTL电视棒、HackRF、BladeRF、USRP、LimeSDR参数对比表：
HackRF One的价格，性能参数却能跟BladeRF甚至USRP媲美！
LimeSDR核心组件：
先上几张特写：
主板长10cm，算上USB接口11.5cm：
主板宽5.7cm:
相对于HackRF、BladeRF、USRP这三款主流SDR硬件（USRP mini除外），体积已经很小巧了。LimeSDR其体积实测只有一个iPhone5s的体积大小！
当插上USB供电后，除了上图显示的两颗绿色LED灯，还有一颗一闪一闪的红色LED灯也在工作。
接下来将分一键快速安装和源码编译安装来使用LimeSDR硬件，推荐使用源码编译安装。
0x01 Mac OSX
1.1 搭建开发环境
Mac OSX当中强烈推荐通过Mac Port 搭建SDR环境，配合源码编译达到最佳效果。
1.通过AppStore安装：Xcode
2.下载安装：XQuartz/X11
3.下载安装：MacPorts
sudoportsearchsdr
sudoportinstallrtl-sdrhackrfbladeRFuhdgnuradiogqrxgr-osmosdrgr-fosphor
完成之后便可从GayHub上clone源码并进行编译安装。
1.2 源码编译LimeSuite
gitclonehttps://github.com/myriadrf/LimeSuite.git cdLimeSuite mkdirbuilddir&&cdbuilddir cmake../ make-j4 sudomakeinstall1.3 源码编译UHD驱动&&增加UHD对LimeSDR的支持
jocover基于UHD给LimeSDR开发了LimeSDR的驱动支持OpenUSRP，把LimeSDR来模拟成USRP B210来使用。
gitclonehttps://github.com/EttusResearch/uhd.git cduhd/host/lib/usrp gitclonehttps://github.com/jocover/OpenUSRP.git echo"INCLUDE_SUBDIRECTORY(OpenUSRP)">>CMakeLists.txt cd../../../ mkdirbuild&&cdbuild cmake.. make-j4 sudomakeinstall1.4 添加环境变量
echo'exportUHD_MODULE_PATH=/usr/lib/uhd/modules'>>~/.bashrc如果用的是iTerm2+zsh则执行：
echo'exportUHD_MODULE_PATH=/usr/lib/uhd/modules'>>~/.zshrc1.5 检测LimeSDR模拟USRP是否成功:
LimeSDR模拟成USRP B210之后最终的效果跟USRP是一样的：
