The authors present a turbo coding scheme for bandwidth-efficient modulation that outperforms turbo coding with Gray mapping by employing Ungerboeck codes as component codes. The scheme can be… Continue Reading
The problem of personalised context aware service selection and composition is an important research area that is addressed within the pervasive service platform being developed by the Daidalos… Continue Reading
oThis paper highlights issues of improved concepts for location information. Starting with a description of the soft location representation the paper presents a tool to easily combine different… Continue Reading
A WiFi-based landmark (LM) is a unique point in the physical space that has a repeatable and identifiable WiFi signature as sensed by a mobile device. We present Lighthouse, a new class of WiFi… Continue Reading
Indoor and urban canyons are application areas that are becoming increasingly important for navigation application. However, achieving the required accuracy and availability is still a challenge.… Continue Reading
A historical perspective of turbo coding and turbo transceivers inspired by the generic turbo principles is provided, as it evolved from Shannon's visionary predictions. More specifically, we… Continue Reading
