冥王星电台,USRP®Embedded Series Radio and Xilinx®Zynq®-Based Radio support packages from Communications Toolbox™ can be used to capture RF signals off the air using Software Defined Radio (SDR) hardware. Using a simple-to-use MATLAB®接口,任何信号都可以捕获到MATLAB工作区中,也可以直接捕获到MATLAB和SIMULINK中的捕获后处理的文件中金宝app®. First, the capture function is used to record the FM Broadcast spectrum to a file which is later read back into a DSP System Toolbox™ spectrum analyzer that highlights peaks corresponding to local broadcast stations. Next, the capture function is used to receive an LTE frame from a local antenna to the MATLAB workspace. LTE Toolbox™ is then used to decode the known physical cell identifier to verify reception.
This video shows you how to capture RF waveforms off the air using MathWorks toolboxes and SDR connectivity.
这是使用捕获方法完成的,该方法可用于将数据从硬件返回到MATLAB工作区和/或直接到文件。
首先,我将使用任何支持的SDR平台直接将FM广播频谱录制到文件。金宝app在这种情况下,冥王星收音机。
然后,我将使用LTE工具箱捕获MATLAB工作区的LTE框架进行分析。为此,我将使用ETTUS E310作为SDR平台。
首先,让我们配置我的附件硬件并设置SDR接收器对象,以从空中接收RF数据。查看接收器属性,我将将中心频率设置为FM广播频谱的中间,并将基带样品速率设置为最大值。
Next, I will call the “capture” method on my receiver object. I specify the capture length and units. I also specify a filename which will be used to store the captured data.
Later, I decide to process the captured data. I create a baseband file reader system object and pass it the name of my generated baseband file.
I pass the output from the baseband file reader into the spectrum analyser to render the data.
在我可以观察到山峰的频谱分析仪in the frequency domain. These correspond to local FM broadcast stations.
Next, I will capture an LTE frame off the air to the MATLAB workspace.
首先,在使用适当的中心频率的MATLAB中设置SDR接收器系统对象之前,先确定附近的天线。
I then call the capture function, setting the capture length to the duration of a single LTE frame.
The capture method returns the data as an output and, once returned, I utilize LTE Toolbox to find the physical cell identifier.
我在这里显示的功能有三个不同的支持软件包可用:用于基于Xilinx Zynq的无线电硬件,模拟设备Pluto Radio和Ettus R金宝appesearch E310和E312。支持软件金宝app包是基于通信工具箱的免费下载。
要查找这些支持软件包,您可以金宝app在自己喜欢的搜索引擎中搜索“ Matlab SDR”;MATLAB和SIMULINK金宝app SDR页面应位于顶部或附近。在页面上,您可以找到有关此视频中显示的支持软件包或我们其他支持的更多详细信息。金宝app
