Heading Routing Protocols: Mobility-Based Routing for Ad-Hoc Networks
In this paper, we present routing algorithms for mobile ad-hoc networks, which exploit the mobility patterns of nodes to provide a robust and long-lived route to destination and reduce flooding and overhead in the network. In the proposed p...
Evaluation of the Capacity of Multiple-Access MIMO Schemes with Feedback in a Small Outdoor Cell
Three algorithms to exploit the multi-user MIMO channel are examined and their system capacity evaluated in the uplink of a small urban cell scenario using measured channel data. An iterative scheme to determine transmit weights that achiev...
Exploiting Multiuser Diversity for MIMO Cellular Systems Using Packet Scheduling and the VBLAST Receiver
Several packet scheduling techniques for the downlink of a multiple-input multiple-output (MIMO) cellular system are investigated. The system capacity for three scheduling are investigated. The system capacity for three scheduling algorithm...
Adaptive MIMO-OFDM for Future Mobile Radio Communications
This paper addresses the topic of bit and power loading in coded MIMO-OFDM systems. Due to the need of designing communication systems with high spectral efficiencies, the combination of multiple antennas at transmitter and receiver with OF...
Exploitation of Diversity in MC-CDMA Systems
MC-CDMA has an additional degree of freedom to exploit diversity compared to OFDMA or MC-TDMA due to spreading. This paper analyzes the achievable BER lower bounds for different MC-CDMA schemes exploiting channel state information (CSI) at ...
MIMO-OFDM: Basic Relations between Coding, Spreading, Multicarrier and Singlecarrier Transmission
This contribution considers the basic relations between coding, spreading, multicarrier and singlecarrier transmission against the background of MIMO-OFDM. MIMO-OFDM is taken, because it can be regarded as a scheme which contains many other...
SPAROGRAM: The spatial augmented reality holographic display for 3D visualization and exhibition
While the 3D graphics technique has found its place for the scientific visualization, especially for medical and biological applications, it has long been speculated that the 3D may not be so much effective as far as the conventional inform...
Benefits of 3D immersion for virtual colonoscopy
Virtual Colonoscopy (VC) is a non-invasive clinical procedure that detects colon cancer in humans. VC seeks to supplement and improve the compliance rates for diagnosed patients, since the traditional optical colonoscopy is more painful, an...
Interactive volume rendering for immersive virtual environments
Immersive virtual environments (IVEs) are an appropriate platform for 3D data visualization and exploration as, for example, the spatial understanding of these data is facilitated by stereo technology. However, in comparison to desktop setu...
Comparison of interactive environments for the archaeological exploration of 3D landscape data
The increasingly widespread availability of high-accuracy terrain models is revolutionizing our understanding of historic landscapes across the globe, yet much of this inherently 3D data is viewed and analyzed using 2D Geographical Informat...
