1. Modeling and Estimation of Phase Noise in Oscillators with Colored Noise Sources
Sammanfattning : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. LÄS MER
2. Phase Noise in Communication Systems--Modeling, Compensation, and Performance Analysis
Sammanfattning : The continuous increase in demand for higher data rates due to applications with massive number of users motivates the design of faster and more spectrum efficient communication systems. In theory, the current communication systems must be able to operate close to Shannon capacity bounds. LÄS MER
3. Detection in Digital Communication Systems with Phase Noise
Sammanfattning : In every communication system, the limitations of the hardware sets a constraint on the overall system performance. More often than not, these limitations are not taken into account during the system design stage where the hardware is considered ideal. LÄS MER
4. Phase-Noise Compensation for Space-Division Multiplexed Multicore Fiber Transmission
Sammanfattning : The advancements of popular Internet-based services such as social media, virtual reality, and cloud computing constantly drive vendors and operators to increase the throughput of the Internet backbone formed by fiber-optic communication systems. Due to this, space-division multiplexing (SDM) has surfaced as an appealing technology that presents an opportunity to upscale optical networks in a cost-efficient manner. LÄS MER
5. Oscillator design in III-V technologies
Sammanfattning : The thesis treats the design of low phase noise oscillators/VCOs in GaAs/InGaP HBT and GaN HEMT technologies. The covered topics are: active device modeling, noise characterization, passive structures, phase noise models, simulation/measurement tools, circuit topologies, and design techniques. LÄS MER
