Students Build Advanced Wireless Networks in Software-Defined Radio Course

Wireless Network is Designed in SDR Course!

Students Test Wireless Network in SDR Course

Five student teams each spent seven weeks during C Term 2012 designing, building, and testing a software-defined digital (SDR) communications system capable of performing jamming-resistant multi-hop wireless networking without any external assistance by a human end-user. According to Professor Wyglinski, “The prototype network consisting of several SDR digital communication systems must be capable of performing multi-hop relaying across at least three wireless nodes, detecting the presence of intentional wireless jamming at any given time during the data transmission, and employing countermeasures to mitigate the effects of the jamming. In order to achieve a successful implementation under real world conditions, each team employed a combination of automatic carrier frequency compensation, frame synchronization, bi-directional communications, spectrum sensing, carrier-sensed multiple access with collision avoidance (CSMA/CA), a simple set of medium access control (MAC) protocols, and dynamic spectrum access (DSA) in their prototype SDR systems.”

Here is a sampling of the work from the students in ECE 4305, C Term 2012:

The generous financial and technical support provided by The MathWorks is gratefully acknowledged. Moreover, the SDR laboratory handouts used for ECE4305 can be freely accessed at the SDR education webpage of the Wireless Innovation Laboratory.
