CRAWDAD up/rf_recordings

In order to be used for examples or projects in communication systems or digital signal processing courses, the radio frequency (RF) signal was recorded from several commercial communication systems and stored in a database. This database contains recordings of radio frequency (RF) signals from several commercial communication systems including AM and FM radio, high definition AM and FM radio, analog and digital TV, Bluetooth, WiFi, GPS, WWV time signal, garage door opener, remote control for toy cars, wireless thermometers, and a wireless serial cable replacement system.last modified : 2008-07-23release date : 2008-07-23date/time of measurement start : 2005-05-16date/time of measurement end : 2005-09-14collection environment : When teaching communication systems, it would be very useful to have access to real signals to illustrate various concepts. For example, when teaching the concept of frequency division multiplexing (assigning different signals to different frequencies), it would make this concept very clear to have a recording of the entire AM radio band, so the students could see that in order to tune in a particular station, the receiver must isolate one of the stations and demodulate it. When teaching frequency hopping systems, it would be interesting to examine the signal from a frequency hopping system such as Bluetooth to witness the signal jumping from one frequency to another. In teaching software-defined radio, it would be interesting to test receivers with real RF signals instead of simulated ones. There are advantages in having the students work with real signals in laboratory courses. But for those students witho ut access to the expensive test equipment or the time to set up the experiments, a database may be the only way to get access to a wide variety of RF signals. The RF signals in the database described in this data set can be used for examples, projects, and homework assignments in a communication systems course to strengthen the link between the concepts and real systems.network configuration : This RF database contains recordings of radio frequency (RF) signals from several commercial communication systems including AM and FM radio, high definition AM and FM radio, analog and digital TV, Bluetooth, WiFi, GPS, WWV time signal, garage door opener, remote control for toy cars, wireless thermometers, and a wireless serial cable replacement system.data collection methodology : The recordings, which were made with a Tektronix RSA3408A Real Time Spectrum Analyzer, can be used to illustrate several important concepts such as various modulation methods, frequency division multiplexing, frequency hopping, direct sequence spread spectrum, and noise.Tracesetup/rf_recordings/rf_signalsTrace set of RF recordings of several communication signals captured by a real time spectrum analyzer.description: This trace set contains recordings of radio frequency (RF) signals from several commercial communication systems including AM and FM radio, high definition AM and FM radio, analog and digital TV, Bluetooth, WiFi, GPS, WWV time signal, garage door opener, remote control for toy cars, wireless thermometers, and a wireless serial cable replacement system.measurement purpose: Educational Usemethodology: - Experimental Setup Most of the RF signals in the database were recorded using the setup shown in [Figure: Experimental Setup for Most of the Database Recordings] consisting of a Tektronix RSA3408A Real Time Spectrum Analyzer and an AOR SA7000 Wideband Antenna (30 KHz - 2 GHz). The Tektronix RSA3408A Real Time Spectrum Analyzer captures the inphase component x(n) and quadrature component y(n) of the complex envelope of the signal as shown in [Figure: Down-Converter in the RSA3408A Real Time Spectrum Analyzer]. The value of the center frequency w_c in [Figure: Down-Converter in the RSA3408A Real Time Spectrum Analyzer] is determined by the center frequency setting of the spectrum analyzer. The decimate operations reduce the amount of data required to represent the signal. The spectrum analyzer stores the inphase and quadrature components as binary files (filename.iqt). The signals can be moved from the spectrum analyzer to a PC using either a USB drive or a computer network. The binary files were converted to text files using a free program from Tektronix called IQTRead, which also corrects for variations in the IF filter response. The resulting files, which are stored in the database, are comma separated value text files (filename.csv) where the first column represents the inphase component x(n), and the second column represents the quadrature component y(n). An example of this format is shown as follows: -0.00110801991035873,-0.00191097592353516 -0.0013188563394699,-0.00225190291528938 -0.00117979401388594,-0.00242685229263694 -0.000852324666543067,-0.00213526999705767 ... A parameter text file (filename.txt) was also created for each recording to document the parameters of the recording such as sampling fr equency, center frequency, etc. The first few lines of a parameter text file are shown as follows: Sampling Frequency (Hz): 64000 Center Frequency (Hz): 1.19e+006 Span (Hz): 50000 ... If desired, the original bandpass signal can be reconstructed from the inphase and quadrature components as shown in [Reconstructing the Bandpass Signal from the Quadrature Components], but usually the complex envelope is processed directly because its data rate is lower.up/rf_recordings/rf_signals TracesAM_Radio: Trace of RF recordings of analog signals from AM radio stations.configuration: Some AM radio stations were recorded as examples of existing analog systems that are easy to demodulate.

为了能在通信系统或数字信号处理课程中用作示例或项目素材，本数据集从多个商用通信系统中录制了射频（radio frequency, RF）信号并存储于数据库中。该数据库包含来自多个商用通信系统的射频信号记录，包括调幅广播（AM radio）、调频广播（FM radio）、高清调幅和调频广播、模拟与数字电视、蓝牙（Bluetooth）、无线局域网（WiFi）、全球定位系统（GPS）、WWV时间信号、车库门开启器、玩具车遥控器、无线温度计以及无线串口电缆替代系统。

采集环境：
在通信系统教学中，获取真实信号以阐释各类概念极为有益。例如，在讲授频分复用（frequency division multiplexing）概念时（即将不同信号分配至不同频率），完整的调幅广播频段记录能让学生清晰理解：要调谐到特定电台，接收机需隔离并解调该电台信号。在讲授跳频系统（frequency hopping systems）时，分析蓝牙等跳频系统的信号可直观观察信号在不同频率间的跳转。在软件定义无线电教学中，使用真实射频信号而非模拟信号测试接收机更具意义。让学生在实验课中接触真实信号有诸多优势，但对于无法获取昂贵测试设备或缺乏实验搭建时间的学生而言，数据库或许是获取多样化射频信号的唯一途径。本数据集所述数据库中的射频信号可用于通信系统课程的示例、项目及作业，以强化理论概念与实际系统间的联系。

网络配置：
该射频数据库包含来自多个商用通信系统的射频信号记录，包括调幅和调频广播、高清调幅和调频广播、模拟与数字电视、蓝牙、WiFi、GPS、WWV时间信号、车库门开启器、玩具车遥控器、无线温度计及无线串口电缆替代系统。

数据采集方法：
这些记录由泰克（Tektronix）RSA3408A实时频谱分析仪采集，可用于阐释多种重要概念，如各类调制方式、频分复用、跳频、直接序列扩频（direct sequence spread spectrum）及噪声。

- 实验装置
数据库中的大多数射频信号通过[图：数据库多数记录的实验装置]所示的装置采集，该装置由泰克RSA3408A实时频谱分析仪和AOR SA7000宽带天线（30 kHz - 2 GHz）组成。泰克RSA3408A实时频谱分析仪采集信号复包络的同相分量x(n)和正交分量y(n)，如[图：RSA3408A实时频谱分析仪中的下变频器]所示。该图中的中心频率w_c由频谱分析仪的中心频率设置决定。抽取操作可减少信号表示所需的数据量。频谱分析仪将同相和正交分量存储为二进制文件（filename.iqt），这些文件可通过USB驱动器或计算机网络从分析仪传输至PC。使用泰克提供的免费程序IQTRead将二进制文件转换为文本文件，该程序还可校正中频（IF）滤波器响应的变化。转换后存储于数据库的文件为逗号分隔值（CSV）文本文件（filename.csv），其中第一列表示同相分量x(n)，第二列表示正交分量y(n)。格式示例如下：
-0.00110801991035873,-00191097592353516
-0.0013188563394699,-0.00225190291528938

-0.000852324666543067,-0.00213526999705767
...
每个记录还配有参数文本文件（filename.txt），用于记录采样频率、中心频率等参数。参数文本文件的前几行示例如下：
采样频率（Hz）：64000
中心频率（Hz）：1.19e+006
带宽（Hz）：50000
...
如需重建原始带通信号，可按[从正交分量重建带通信号]所示方法利用同相和正交分量实现，但通常直接处理复包络即可，因其数据率更低。
