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
