Performance function modeling for statistical design of integrated circuits
(1993)
The primary objective of this dissertation is to develop new performance function modeling strategies to be used for statistical design of integrated circuits. The major bottle-neck during statistical circuit design is ...
Synchronization for optical overlapping pulse-position modulation systems
(1991)
In direct-detection optical communication, overlapping pulse-position modulation (OPPM) was shown to exhibit some advantages over pulse-position modulation (PPM). OPPM is a modification of PPM allowing overlapping between ...
Development and analysis of a hybrid random/token access protocol for high speed local area networks
(1994)
In this dissertation, we develop and analyze a local area network (LAN) protocol aimed at high data rates and that supports integrated traffic. We make use of a unidirectional dual bus as the network topology and develop ...
Multilevel codes for PSK signaling over the Rayleigh fading channel
(1992)
In this research we investigate the application of multilevel codes to the Rayleigh fading channel, the modulation form at being the MPSK constellation. The first part of the study reveals that effectively twice the diversity ...
A novel signal processing algorithm for FFPI and its sensor system application
(1994)
A novel digital signal processing algorithm using a pulse-modulated, fiber-optic Fabry-Perot sensor system with temperature as the measurand is devised and implemented. Measurement of change in temperature makes use of the ...
Fiber-optic frequency shifter
(1993)
A new type of fiber-optic frequency shifter was studied theoretically and experimentally. It consists of a birefringent optical fiber embedded in an aluminum acoustic waveguide. Light with a wavelength of 1.3 μm enters ...
Analysis of the expansion properties of the hypercube network
(1994)
The recent advent of VLSI technology has made it possible to build a parallel computing system which has combined many relatively inexpensive VLSI processors together into multiprocessor systems. One key obstacle which has ...
Timing analysis of VLSI circuits using symbolic and visualization technics for practical applications
(1992)
In this dissertation, we apply the linear RC delay modeling techniques to empirically model the timing delay in the CMOS VLSI circuits. The multi-dimensional function of various circuit combinations and device parameters ...
Robust tree coding combined with harmonic scaling of speech
(1992)
Efficient speech coders using tree coding combined with harmonic scaling are designed at the rates of 6.4 kilobits/sec (kbps) and 4.8 kbps. A time domain harmonic scaling algorithm (TDHS) is used to compress input speech ...
Optical control in GaAs microwave semiconductor devices
(1994)
New types of Traveling Wave Photodetectors (TWPDs) are designed using coplanar stripline structures, fabricated on semi-insulating GaAs substrates, and characterized by microwave and optical methods. In this traveling wave ...
