Architecture and Algorithm for a Stochastic Soft-output MIMO Detector
(IEEE, 2007-11-01)
In this paper, we propose a novel architecture for a soft-output stochastic detector in multiple-input, multiple-output (MIMO) systems. The stochastic properties of this detector are studied and derived in this work, and ...
Preamble-based Symbol Timing Estimation for Wireless OFDM Systems
(IEEE, 2007-11-01)
We propose a timing estimation scheme that reduces computational complexity while achieving performance comparable to the autocorrelation method
commonly employed at the wireless receiver. The proposed method is based on ...
Improved haptic fidelity via reduced sampling period with an FPGA-based real-time hardware platform
(2007)
The challenge of displaying stiff virtual walls in a haptic interaction is the inspiration for this document. The fidelity of their implementation necessitates high virtual stiffness integrated with passive device behavior. ...
The geometry of low-dimensional signal models
(2007)
Models in signal processing often deal with some notion of structure or conciseness suggesting that a signal really has "few degrees of freedom" relative to its actual size. Examples include: bandlimited signals, images ...
Distributed multi-scale data processing for sensor networks
(2007)
Wireless sensor networks provide a challenging application area for signal processing. Sensor networks are collections of small, battery-operated devices called sensor nodes, each of which is capable of sensing data, ...
Physical layer algorithms with limited feedback: Power control and coding strategies
(2007)
The uncertainty in the received signal is the main limiting factor for the throughput of any communication system with limited resources. In this thesis we analyze the potential gain in throughput by managing channel ...
On the impact of receiver quantization on the performance of wireless communication systems
(2007)
The overall objective of this dissertation was to determine the influence of footwear sole hardness on slip initiation and falls. To achieve this goal, three separate studies were undertaken. The purpose of the first study ...
Code design for the relay channel
(2007)
The design of wireless communication networks is based on the premise that networks are collections of reliable point-to-point links between communicating nodes. Such a communication model, although simple, is inefficient ...
A performance study of deployment factors in wireless mesh networks
(2007)
This thesis presents a measurement-parameterized performance study of deployment factors in wireless mesh networks using four performance metrics: client coverage area, backhaul tier connectivity, protocol-dependent ...
Reconfigurable heterogeneous DSP/FPGA based embedded architectures for numerically intensive computing workloads
(2007)
Telecommunications and multimedia form a vast segment of the embedded systems market. Variations in standards coupled with the desire for software programmability often result in software based implementations executing ...
