ECE 463: Digital Communications Laboratory - Fall 2018


Course Description:

The goal of this course is to give students hands-on experience in the design, configuration and evaluation of digital communication systems through software defined radios. The course will introduce students to various components of a digital transceiver. It will also cover various Internet of Things (IoT) communication technologies used today. Students will learn through lab driven experiments on USRP software defined radios.
