Software Defined Radio: Introductory Workshop on Spectrum, Radio Frequency, Related Tools, Software
July 8, 2017 @ 10:00 am - 2:00 pm
I. Goal: introduce mid or late career IEEE members and others who may be HW, SW engineers, EE, scientists, others to spectrum, spectrum clutter problem, Software Defined Radio (SDR) as a new (last 10-15 years) area
II. Motivation behind SDR and Problems addressed by SDR
III. Workshop Topics
A. Components of a SDR
1. transmitter, receiver, block diagrams, generally how they work..
2. Component blocks: ADC, DAC, FPGA, LNA, PA
B. Observe via demos
-
RF signal identification, frequency, encoding e. g. OOK, on-off keying in Subaru key fobs vs FSK or frequency-shift-keying in Toyota, Kia
-
signal components e. g. frequency, magnitude, noise
-
FFT and filtering in action
-
spectrum utilization, access, congestion, conflicts
Demonstrations
1. Aircraft, Satellite tracking
2. Hot spots (WiFi, Cellular)
3. Jammer using a microwave oven
4. Locate areas of good reception, nulls, and optimize performance
for good reception of WiFi networks
5. Digital Patterns 315, 433 MHz
C. Near Field and Far Field regime of operation using antennas
D. Antenna Types, Patterns, Similarities & Differences
E. Digital signal processing vs FPGAs, other strategies; current software tools e. g. Matlab, Python, C++, GNU radio as an example, Linux environment
F. EMC Test equipment
G. IoT’ – Internet of Things
H. Test Requirements (RTSA, NA, DSO)
I. Compliance (FCC and other)
