Basics of software defined Radios and Practical Applications

Indian Institute of Technology Roorkee and NPTEL via Swayam

This course may be unavailable.


Software-defined radio (SDR) is an inherent part of the modern communication system, where many processes, which used to be implemented in hardware, are defined in the 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.INTENDED AUDIENCE : Both UG/PG can take this course, Industry people can also register. PREREQUISITES : A background in electrical engineering helps to some extent, but this is not requiredINDUSTRY SUPPORT : Telecommunication Industry, Defence Industry , Aeronautical Industry, and Space Industry.


Week1: Basic components of software defined radios, Software defined radio architectures-Part A, Software defined radio architectures- Part BWeek2: Distortion parameters-Sources and metrics of distortion in a transceiver,Nonlinear distortion and nonlinearity specifications, Power amplifiers: Nonlinear Distortion in Transmitted SignalsWeek3: Power amplifier Line-up for linearity & power requirement calculations,Linearization Techniques for nonlinear distortion in SDR, Predistortion Techniques for nonlinear distortion in SDRWeek4: Digital Predistortion Techniques for Linear/Nonlinear Distortion
