Precoding for Interference Management in Wireless and Wireline Networks
(2018-02-27)
Multiple users compete for a common resource like bandwidth to communicate
data in interference networks. Existing approaches in dealing with interference
limit the rate of communication due to paucity of shared resources. ...
Design and Development of a Passive Infra-Red-Based Sensor Platform for Outdoor Deployment
(2018-04-23)
This thesis presents the development of a Sensor Tower Platform (STP) comprised of an array of Passive Infra-Red (PIR) sensors along with a classification algorithm that enables the STP to distinguish between human intrusion, ...
