Architecture and algorithms for scalable mobile QoS
Supporting Quality of Service is an important objective for future mobile systems, and requires resource reservation and admission control to achieve. In this thesis, we introduce a scalable scheme to admission control ...
Efficient VLSI architectures for multiuser channel estimation in wireless base-station receivers
(Kluwer Academic Pubishers, 2002-06-20)
This paper presents a reduced-complexity, fixed-point algorithm and efficient real-time VLSI architectures for multiuser channel estimation, one of the core baseband processing operations in wireless base-station receivers ...
New Bayesian Model Averaging Framework for Wavelet-Based Signal Processing
This paper develops a new signal modeling framework using Bayesian model averaging formulation and the redundant or translation-invariant wavelet transform. The aim of this framework is to provide a paradigm general enough ...
Real-Time DSP Multiprocessor Implementation for Future Wireless Base-Station Receivers
The convergence of cellular phones, the Internet, and laptop computers into a single small, lightweight, wireless information appliance drives a need for a high data rate, low-power digital wireless communication link to ...
Wireless @ Wired Speeds
This is a poster from the first 100x100 project meeting. It outlines some basic concepts in MIMO algorithm and system design at a relatively high, accessible level.
Channel Equalization Algorithms for MIMO Downlink and ASIP Architectures
Processors for mobile handsets in 3G cellular systems require: high speed, flexibility and low power dissipation. While computationally efficient, ASIC processors are often not flexible enough to support necessary ...
Derivation and Application of Nonlinear Analytical Redundancy Techniques with Applications to Robotics
Derivation and Application of Nonlinear Analytical Redundancy Techniques with Applications to Robotics Fault detection is important in many robotic applications. Failures of powerful robots, high velocity ...
ASIP Architecture for Future Wireless Systems: Flexibility and Customization
Efficiency and flexibility are crucial features of the processors in the next generation of wireless cellular systems. Processors need to be efficient in order to satisfy real-time requirements for very demanding algorithms ...
Estimation-Quantization Geometry Coding Using Normal Meshes
We propose a new algorithm for compressing three-dimensional triangular mesh data used for representing surfaces. We apply the Estimation-Quantization (EQ) algorithm originally designed for still image compression to the ...
Power optimization in multiple transmit antenna communication systems
We explore optimal ways of communicating (with a power constraint) over multiple antenna communication systems by managing spatial power distribution. We find that Mutual Coupling (MC), the interaction between antenna ...
