Performance evaluation of the third generation TD-SCDMA system.
(2004)
Firstly, a basic reverse TD-SCDMA system is setup, including a transmitter, a receiver and a channel. Within the receiver model, a specific soft Viterbi decoding algorithm is developed. Secondly, the system synchronization ...
Performance enhancement of large scale networks with heterogeneous traffic.
(2006)
Finally, these findings are applied towards improving the performance of the Differentiated Services architecture by developing a new Refined Assured Forwarding framework where heterogeneous traffic flows share the same ...
A high-performance inner-product processor for real and complex numbers.
(2003)
A novel, high-performance fixed-point inner-product processor based on a redundant binary number system is investigated in this dissertation. This scheme decreases the number of partial products to 50%, while achieving ...
Development of lead-chalcogenide mid-infrared light emitting devices.
(2007)
The research described by this dissertation has focused on the fabrication and design, for the improvement of lead chalcogenide lasers. The ultimate goal was to develop TE-cooled single-mode continuous wave Mid-IR laser ...
Modeling and compensation of CDMA power amplifiers.
(2001)
The efficient operation of a linear high power amplifier (HPA) often results in enhancing its inherent nonlinear behavior. This nonlinear behavior causes co-channel and adjacent channel interference due to intermodulation ...
A microscopy scanning system for clinical chromosome diagnostics.
(2007)
During the course of this research, the following papers were authored or co-authored: (1) X. Wang, B. Zheng, M. Wood, S. Li, W. R. Chen, and H. Liu, "Development and Evaluation of Automated Systems for Detection and ...
Fir filter design for area efficient implementation /
(2005)
In this dissertation, a variable precision algorithm based on sensitivity analysis is proposed for reducing the wordlength of the coefficients and/or the number of nonzero bits of the coefficients to reduce the complexity ...
Hirschman optimal transform least mean square adaptive filters.
(2007)
Abstract not available.
A hierarchical, multiscale texture segmentation algorithm for real-world scenes.
(2001)
We also develop a way of objectively evaluating texture segmentation algorithms on natural and synthetic texture patches. Finally, our multiscale segmentation approach is demonstrated on several families of real-world ...
A free-space optical communications link to an unmanned aerial vehicle.
(2005)
Free-space optics (FSO) is an optical communications technology in which information is transmitted through the atmosphere on modulated optical beams. At the time of the development of FSO, it was envisioned to be a possible ...
