Software Defined Radio (SDR) - Course Overview

The course duration is 40 academic hours and will be delivered over 8 meetings of 5 academic hours each. This is a comprehensive and intensive course intended for electrical engineers, system engineers, computer science engineers, signal processing and algorithms developers etc. (see the course syllabus).
The course, is presented by leading technical experts from industry and academia with many years of experience (see Lecturers).
During the first two meetings, led by Dr. Shmuel Miller, the theory background is established:
Designing real world SDR receivers for analog and digital communication systems based on advanced DSP and digital communications theory.
The rest of the 6 sessions are entirely devoted to Simulation examples and hands-on Design Exercises.
These sessions are delivered in a “computers classroom” by two instructors simultaneously: Led by Dr. Miller with the assistance of Mr. Profis.
First the Matlab-Simulink tools are introduced, followed by Simulation examples and Design Cases. Homework exercises contribute to the continuous learning process, and greatly assist in acquiring the analysis and design skills by the participants. Integration RF hardware with a modern simulation environment such as Matlab – Simulink enables implementing and learning SDR by personal experiencing and hands-on self-work!
The provided SDR hardware can be used to acquire and sample RF signals transmissions in the frequency rang 25MHz to 1.75 GHz (via cable or off the air) and the Matlab – Simulink environment is used to develop demodulators and measurement and presentation tools using DSP algorithms.
Modulations covered in this Course include: AM, FM, SSB, OOK, FSK, M-PSK and QAM. The user may receive and analyze the spectrum of signals, including: FM radio, VHF/UHF band signals, ISM signals, GSM, 3G and LTE mobile radio, GPS and satellite signals and any library-signal transmitted in class by the R&S vector signal generator in the above frequency band.
During the course we introduce the participants to SDR signal processing methods by viewing and analyzing down-converted RF signals in the time and frequency domains, and then provide extensive DSP enabled SDR design cases. In addition to signal reception and demodulation the course includes also the theory and implementation of system signal-processing functions including tracking loops (AGC, PLL) in reception, and linearization (in transmission).

SDR-Software Defined Radio from Theory to Practice

Lecture by

Dr. Shmuel Miller

at the BMR2017 the Israeli Wireless symposium

Abstract​
A Software-Defined-Radio (SDR) design methodology employing Matlab/Simulink, an RF front-end (FE) and a PC is presented and demonstrated. Analog and digital modulation receiver examples are used to facilitate the flexibility and effectiveness of this approach.
