6. Language Support for Controlling Timing-Based Covert Channels
Sammanfattning : The problem of controlling information flow in multithreaded programs remains an important open challenge.A major difficulty for tracking information flow in concurrent programs is due to the internal timing covert channel. LÄS MER
7. Successive Interference Cancellation in DS-CDMA Systems
Sammanfattning : There is every indication that direct-sequence code division multiple access (DS-CDMA) will be one of the multiple access schemes for the third generation wireless mobile systems. CDMA is a flexible multiple access method suitable for supporting many new services (speech, data, video, etc), which are becoming increasingly important for mobile communications. LÄS MER
8. Open Quantum Systems : Effects in Interferometry, Quantum Computation, and Adiabatic Evolution
Sammanfattning : The effects of open system evolution on single particle interferometry, quantum computation, and the adiabatic approximation are investigated.Single particle interferometry: Three concepts concerning completely positive maps (CPMs) and trace preserving CPMs (channels), named subspace preserving (SP) CPMs, subspace local channels, and gluing of CPMs, are introduced.

9. On Soft Decoding and Robust Vector Quantization
Sammanfattning : This thesis considers vector quantization for noisy channels. Vector quantization (VQ) is an important technique for block-based source coding, with applications in, e.g., speech and image coding. LÄS MER
10. The Block Error Rate in Block Interference Channels and its Applications to Medium Access Control
Sammanfattning : This thesis may be distinguished into two interdependentparts. The first part outlines the outcome of our efforts toconstruct accurate and yet simple models that account for the probability of successful reception of a packet for a wide range of physical layer parameters. LÄS MER
