Constellation Constrained Capacity For Two-User Broadcast Channels
(2011-07-12)
A Broadcast Channel is a communication path between a single source and two or more receivers or users. The source intends to communicate independent information to the users. A particular case of interest is the Gaussian ...
A Low-Complexity Intrusion Detection Algorithm For Surveillance Using PIR Sensors In A Wireless Sensor Network
(2011-07-12)
A Wireless Sensor Network (WSN) is a dense network of autonomous devices (or motes) with sensors that cooperatively monitor some physical or environmental conditions. These devices are resource constrained -limited memory, ...
A Dynamic Security And Authentication System For Mobile Transactions : A Cognitive Agents Based Approach
(2011-01-25)
In the world of high mobility, there is a growing need for people to communicate with each other and have timely access to information regardless of the location of the individuals or the information. This need is supported ...
Rate-Distortion Performance And Complexity Optimized Structured Vector Quantization
(2011-02-09)
Although vector quantization (VQ) is an established topic in communication, its practical utility has been limited due to (i) prohibitive complexity for higher quality and bit-rate, (ii) structured VQ methods which are not ...
