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.

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.

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.

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.

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

- 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.

The folder RF_Recordings contains the recordings in two different formats. The
RSA3408A Real Time Spectrum Analyzer stores data in a compact binary format
(filename.iqt). The recordings are also distributed in comma separated value text files
(filename.csv), which is an ASCII format that can be read by many different software
packages. (The .csv files are much larger than the .iqt files.) 
Each recording also has a parameter text file (filename.txt) that documents 
the parameters of the recording such as sampling frequency, center frequency, etc.

The same folder contains the MATLAB program iqtread.m, which can be used to load

The folder RF_Recordings contains the recordings in two different formats. The
RSA3408A Real Time Spectrum Analyzer stores data in a compact binary format
(filename.iqt). The recordings are also distributed in comma separated value text files
(filename.csv), which is an ASCII format that can be read by many different software
packages. (The .csv files are much larger than the .iqt files.) 
Each recording also has a parameter text file (filename.txt) that documents 
the parameters of the recording such as sampling frequency, center frequency, etc.

The same folder contains the MATLAB program iqtread.m, which can be used to load 
the .iqt files, which is much faster than loading the .csv files.

Date and Time of Recording: 2005/05/23@12:43:27
Recorded by: Joseph P. Hoffbeck (hoffbeck@up.edu) and Andrew Melton, Univeristy of Portland
Experimental Setup: Tektronix RSA3408A Real-Time Spectrum Analyzer and AOR SA7000 Wideband Antenna
Notes: Radio Shack Wireless Thermometer Catalog Number 63-1026: 79.2 degress

The folder RF_Recordings contains the recordings in two different formats. The
RSA3408A Real Time Spectrum Analyzer stores data in a compact binary format
(filename.iqt). The recordings are also distributed in comma separated value text files
(filename.csv), which is an ASCII format that can be read by many different software
packages. (The .csv files are much larger than the .iqt files.) 
Each recording also has a parameter text file (filename.txt) that documents 
the parameters of the recording such as sampling frequency, center frequency, etc.

The same folder contains the MATLAB program iqtread.m, which can be used to load 
the .iqt files, which is much faster than loading the .csv files.

Trace of RF recordings of signals from 900MHz 9600 baud wireless serial port.

The configuration of each recording (the recording name also used as filename) is as follows:

Sampling Frequency (Hz): 1.28e+007
Center Frequency (Hz): 9.14e+008
Span (Hz): 1e+007
Length of Recording (Number of Samples): 6399488
Length of Recording (Seconds): 0.49996
Filename of Original Binary .iqt File: wireless_serial_port.iqt
Filename of .csv Text File: wireless_serial_port.csv

Experimental Setup: Tektronix RSA3408A Real-Time Spectrum Analyzer and AOR SA7000 Wideband Antenna
Notes: This is a recording of a transmission from a MaxStream 9xStream 900MHz 9600 baud
 Wireless OEM Module. It uses frequency hopping on frequencies from 902 - 928 MHz.
 The serial data throughput is 9600 bps and the RF Baud Rate is 10000 bps.
 The data being sent in this transmission is "The secret word is MaxStream"
