6. Coherent Optical Transmission Systems : Performance and Coding Aspects
Sammanfattning : Since the invention of fiber-optic systems in the 1970s, user demand has driven innovation forward, and each new generation of products has achieved higher data rates than its predecessor. Today, the most promising approach for further increasing data rates is coherent transmission with multi-level modulation and digital signal processing (DSP). LÄS MER
7. On Linear Transmission Systems
Sammanfattning : This thesis is divided into two parts. Part I analyzes the information rate of single antenna, single carrier linear modulation systems. The information rate of a system is the maximum number of bits that can be transmitted during a channel usage, and is achieved by Gaussian symbols. LÄS MER
8. Bone conducted sound transmission for communication systems
Sammanfattning : Bone conducted (BC) sound is vibrations in the skull bone that are transmitted to the cochlea and perceived as sound, originating from a sound field or a vibration transducer. This transmission path can be advantageous for communication systems in some situations, e.g. LÄS MER
9. On Noise Generation and Dynamic Transmission Error of Gears
Sammanfattning : Noise from heavy trucks is an important environmental issue. Several sources contribute to the total noise level of a vehicle, such as the engine, gearbox, tires, etc. The tonal noise from the gearbox can be very disturbing for the driver, even if the noise level from the gearbox is lower than the total noise level.

10. Design Aspects of Coordinated Multipoint Transmission : A Study of Channel Predictions, Resource Allocation, User Grouping and Robust Linear Precoding for Coherent Joint Transmission
Sammanfattning : Shadowed areas and interference at cell borders pose great challenges for future wireless broadband systems. Coordinated Multipoint (CoMP) coherent joint transmission has shown the potential to overcome these challenges by turning harmful interference into useful signal power. LÄS MER
