This thesis considers the design of receivers for multi-user communication systems based on asynchronous direct-sequence code-division multiple-access (DS-CDMA). Its primary aim is to improve current receiver designs which exhibit shortcomings in systems using long sequence spreading (where the spreading sequence…

Wireless digital data system designers have formidable future design challenges in order to provide the mobile user with a quality of service comparable to that of a wireline system in such metrics as responsiveness, quality, and throughput. The goal of…

This dissertation addresses the impact of integrated services on future third generation wireless DS-CDMA networks. The first part of the research characterizes the multiple-access interference (MAI) in an integrated DS-CDMA system. The system model is designed to accommodate bursty packed-based…

In the recent years, we have witnessed an increased interest in space-time coding, because of its effectiveness in overcoming the impairments due to the signal fading phenomenon. A large number of such codes require channel knowledge for decoding. Therefore, research…

Voltage-Source Converters form the basic modules of a class of power electronic controllers of Flexible AC Transmission Systems (FACTS) which include the STATic COMpensator (STATCOM), the Static Synchronous Series Compensator (SSSC) and the Unified Power Flow Controller (UPFC). The mathematical…

This thesis deals with the control and protection of Multi-Terminal DC (MTDC) transmission systems based on Voltage-Source Converters (VSCs). The MTDC system enables several AC systems to be integrated by way of a DC network. Potential applications of the MTDC…

This thesis aimed to provide a knowledge base and methodologies to help minimize electromagnetic interference (EMI) in healthcare. Two methods were developed, for the first time, to quantify EMI risk due to radio frequency (RF) sources in hospitals. The first…
