Design of Reconfigurable Baseband Filter
(2010-11-19)
With the rapid development of worldwide wireless communication networks, mobile terminal devices compatible for multi-standard and various applications are needed. Software defined radio is a suitable answer to those demand. ...
Selective Spectrum Analysis and Numerically Controlled Oscillator in Mixed-Signal Built-In Self-Test
(2010-12-09)
Built-In Self-Test (BIST) offers a system the ability to test itself. Though it introduces inevitable extra cost for the added hardware, it also makes it possible to monitor, measure and calibrate the system on the fly ...
Adaptive Estimation and Equalization of Doubly-selective Fading Channels using Basis Expansion Models
(2010-12-07)
Wireless channels, due to multipath propagation and Doppler spread, are characterized by frequency- and time-selectivity, so-called doubly-selective wireless channels. In this dissertation, we concentrate on adaptive channel ...
Test time optimization in scan circuits
(2010-11-10)
As circuit sizes increase with scale down in technology, the time required to test the circuits also increases. Expensive automatic test equipment (ATE) is used to test these circuits and the cost of testing becomes a ...
Mobility Modeling, Prediction and Resource Allocation in Wireless Networks
(2010-10-29)
Rapid increase in the number of mobile and wireless users has created greater loads on legacy networks. Also, increased miniaturization of computing devices has led to an influx of handheld gadgets. Mobile users now wish ...
A Pre-distortion Technique for OTA-C Filter Design
(2010-11-16)
The growing demand of continuous filters in portable electronic equipment, wireless receivers and continuous-time (CT) analog-to-digital converters (ADCs) has spawned a strong research interest from industry and academia. ...
Protocol Design and Performance Issues in Cognitive Radio Networks
(2010-09-24)
A cognitive radio is a frequency agile wireless communication device based on software defined radio that enables dynamic spectrum access. cognitive radio represents a significant
paradigm change in spectrum regulation ...
Lane Detection, Calibration, and Attitude Determination with a Multi-Layer Lidar for Vehicle Safety Systems
(2010-11-05)
This thesis develops a lane detection algorithm which extracts lane markings from the road's surface in an effort to ascertain the lateral position of the vehicle in the lane using a lidar, with the goal of being incorporated ...
3D Simulation of SEU in SiGe HBTS and Radiation Hardening by Design
(2010-07-27)
This thesis presents 3-D simulation of Single Event Upset (SEU) in IBM 5HP and 8HP heterojunction bipolar transistors (HBT). SiGe HBT has been attractive for space applications because
of its high performance. SiGe HBTs ...
