SDR- Software Defined Radio
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.
