Data hiding and detection in Office Open XML (OOXML) documents
Raffay, Mohammad Ali (2011-03-01)With the rapid development and popularity of information technology, criminals and mischievous computer users are given avenues to commit crimes and malicious activities. One of the commonly used tactics, called steganography, ... -
Joint uplink-downlink beamforming in multi-antenna relaying schemes
D'Souza, Olaf Manuel (2009-11-01)The thesis examines the problem of joint receive and transmit beamforming for a wireless network which consists of one relay node equipped with multiple antennas. The transmitter and the receiver are single antenna ... -
Learning-based adaptive design for dynamic spectrum access in cognitive radio networks.
Zandi, Marjan (2014-10-01)This thesis is concerned with dynamic spectrum access in cognitive radio networks. The main objective is designing online learning and access policies which maximize the total throughput of the secondary users in a ... -
Power-optimal network beamforming in single-carrier asynchronous two-way relay networks
Bastanirad, Sahar (2015-09-01)In this thesis, we consider a single-carrier asynchronous two-way relay network, where the relays employ amplify-and-forward (AF) signaling in a multiple access broadcast channel (MABC) protocol to enable a bi-directional ... -
Secure and compromise-resilient architecture for advanced metering infrastructure
Alfaheid, Khalid (2011-03-01)In recent years, the Smart Grid has grown to be the solution for future electrical energy that promises to avoid blackouts as well as to be energy efficient, environmentally and customer-friendly. In Smart Grid, the ... -
Social-based trustworthy data forwarding in vehicular delay tolerant networks
