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 06 - Software-Defined Radio Architecture, Part IV |
This lecture discusses the requirements of 4G/5G communication systems where data speed and hence signal bandwidth puts a constraint on utilization of conventional architectures. Concepts such as over and under sampling are discussed as a possible solution.
