EE49 Lab 5: Building a Wireless Packet Transmitter and Receiver

Goal

We’ve spent the last 4 labs learning about various aspects of communications.  The aim of the course project is to bring it all together to design and implement your very own, custom communication protocol. Part 1 of this lab will require you, as a class, to create a protocol specification which everyone agrees upon. Part 2 will be implementing it!

Course Overview

This lab is from a course developed at Stanford University entitled Building Networked Systems. The course was first taught with a trial group of students in the Spring 2011 quarter. With the software/hardware combination of LabVIEW and the NI USRP, students were able to build and explore each element of a complete communications system signal chain. The course progression covered topics including channel coding, modulation, demodulation, timing recovery and culminated with students building their own protocol.

Course evaluations affirmed that students were highly engaged in and benefited greatly from the EE 49 class.  “The course evaluations for our class were fantastic,” said Katti. “Students rated the class 4.94/5.0, likely making it one of the highest rated among all classes in the School of Engineering at Stanford.”  To learn more about the course view the case study entitled: Designing Hands-On Wireless Communications Labs With the NI Universal Software Radio Peripheral and ....

These materials are considered a work-in-progress and reflect the first run of the course.  The course is anticipated to run again in the Spring of 2012.
