Software Defined Radio: Introductory Workshop on Radio Frequency Spectrum, Related Tools, Software
December 9, 2017 @ 10:00 am - 2:00 pm EST
Co-sponsored by: Washington and NOVA Reliability Society, Baltimore Section, IEEE
I. Goal: introduce IEEE members and others who may be HW, SW engineers, EE, scientists, others to spectrum, spectrum clutter problem, Software Defined Radio (SDR) and Cognitive Radio.
II. Move to 5G; HW SW tradeoffs in radio, other design; SDR and Cognitive Radio in this context
III. Workshop Topics
A. SDR compared with other radio implementations
1. transmitter, receiver, block diagrams, generally how SDRs work..
2. Component blocks which may or may not be in the SDR: 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
1. identification of signals (air craft location, key fobs, other)
2. Locate areas of good reception, nulls, and optimize performance for good reception of WiFi networks
3. Digital Patterns at 315, 433 MHz
C. Antenna Types, Patterns, Similarities & Differences
D. Cognitive Radio: what it is, how it operates
10-10:30 Registration, networking, coffee and bagels
10:30-11:30 5G today (what it is, how we got here, directions); positioning SDR, cognitive radio, IOT, EMC, other developments today
11:45-1:15 Demonstrations and discussion
1:15-1:30 Discussion on who would like what type of workshop next e. g. a DIY, build boards, install SDR receivers?
1:55 Good by’s — the Electronic Museum closes at 2.
Room: large conference room
Bldg: National Electronics Museum
