1. mm-Wave Data Transmission and Measurement Techniques: A Holistic Approach
Sammanfattning : The ever-increasing demand on data services places unprecedented technical requirements on networks capacity. With wireless systems having significant roles in broadband delivery, innovative approaches to their development are imperative. LÄS MER
2. Modeling and Compensation of Polarization Effects in Fiber-Optic Communication Systems
Sammanfattning : Optical communication systems that exploit the orthogonality between two polarizations of light convey information over optical fibers by modulating data over the two polarizations. In an idealized scenario, the two polarizations propagate through the fiber without interfering. LÄS MER
3. Modeling and Tracking of Stochastic Polarization Drifts in Fiber-Optic Systems
Sammanfattning : In the past decade, accessing information has become easier than ever, leading to a rapid growth in popularity of social media, online gaming, and multimedia broadcast systems. These and other services put pressure on the Internet service providers to support high-speed Internet connections and motivate the need for faster communication systems. LÄS MER
