6. Voronoi Constellations for Coherent Fiber-Optic Communication Systems
Sammanfattning : The increasing demand for higher data rates is driving the adoption of high-spectral-efficiency (SE) transmission in communication systems. The well-known 1. LÄS MER
7. Error and Traffic Control for High-Speed Networks
Sammanfattning : The Internet evolves rapidly, both in terms of the applications that use it and the networks that carry the traffic. This creates many important research tasks, both to adapt the networks that carry the traffic to work well together with the Internet protocols and to make the protocols robust to tolerate various underlying networks. LÄS MER
8. HARQ Systems: Resource Allocation, Feedback Error Protection, and Bits-to-Symbol Mappings
Sammanfattning : Reliability of data transmission is a fundamental problem in wireless communications. Fading in wireless channels causes the signal strength to vary at the receiver and this results in loss of data packets. To improve the reliability, automatic repeat request (ARQ) schemes were introduced. LÄS MER
9. On Probabilistic Shaping and Learned Decoders with Application to Fiber-Optic Communications
Sammanfattning : We live in an ubiquitously connected world whose backbone are optical fibers. Achieving high spectral efficiencies and hence high transmission rates requires a careful combination of forward error correction (FEC) and higher-order modulation. This is referred to as coded modulation. LÄS MER
10. Internet Video Transmission
Sammanfattning : The Internet has rapidly evolved from being a scientific experiment to a commercial network connecting millions of hosts that carries traffic generated by a large amount of applications with diverse requirements. Its architecture was however designed to enable efficient point-to-point delivery of bulk data, and can not provide statistical guarantees on the timely delivery of delay sensitive data such as streaming and real-time multimedia.
