Basics of Software-Defined Radios and Practical Applications
Basics of Software-Defined Radios and Practical Applications. Instructor: Dr. Meenakshi Rawat, Department of Electronics and Communication Engineering, IIT Roorkee. Software-defined radio (SDR) is an inherent part of modern communication system, where many processes, which used to be implemented in hardware, are defined in software domain for flexibility and configurability. This course describes various components of software-defined-radios with the understanding of their limitation and application of software-defined-solutions to overcome such limitations. Understanding the interplay of analog and digital signal processing for power as well as spectrum efficient transmission and reception of signal leads to an optimized, yet, practical radio solution. This course will allow students to understand (1) the terminology used in industrial data-sheets and (2) motivation for selecting appropriate commercial solutions for a practical transceiver design.

Lecture 01 - Foundation for Software-Defined Radio |
This lecture deals with the requirement of SDR and building blocks of conventional radio system. The digital and analog processing in a transmitter is discussed. Succinctly and superficially, the communication engineering concepts such as modulation scheme are described, which dominate the choices for radio design, are also touched upon.
