New Multi-User OFDM Scheme: Braided Code Division Multiple Access
In this paper, we present a new multiple access scheme using OFDM modulation which we call braided code division multiple access (BCDMA). The principle behind this novel multiple access technique is to combine in one single scheme a very efficient error correction code, interleaving for channel diversity exploitation and, simultaneously, a multiple access method for a large number of users.

User related assessment of Safe Cruise and Speed Support (VCC)
The aim of the user related assessment was to study perceived advantages, disadvantages, usefulness, trust, acceptance, willingness to have and pay for the driver assistance systems: Safe Cruise and Speed Support developed by VCC within the framework of SECONDS subproject. Due to restrictions in driving in real traffic, assessment activities were limited to driving on a test track by naïve test dr

Interleaver design for turbo codes based on the performance ofiterative decoding
The performance of a turbo code is dependent on two properties of the code: its distance spectrum and its suitability to be iteratively decoded. Both these properties are dependent on the specific interleaver used in the turbo-coding scheme. This paper describes a strategy for interleaver design that includes a criterion for the performance of iterative decoding. This criterion is based upon corre

Systematics, phylogeography and polyploid evolution in the Dactylorhiza maculata complex (Orchidaceae)
Popular Abstract in Swedish Jungfru Marie nycklar och skogsnycklar: systematik, evolution och invandringshistoria Jungfru Marie nycklar (ssp. maculata) och skogsnycklar (ssp. fuchsii) bildar tillsammans ett mångformigt och vittspritt artkomplex inom det eurasiska orkidésläktet Dactylorhiza. I min avhandling har jag kommit fram till flera allmänna och biologiskt viktiga slutsatser rörande artbildnThe aim of this thesis was to investigate and describe different aspects of variation in the Dactylorhiza maculata complex and to relate the variation patterns to underlying biological processes such as Quaternary migration history, hybridization and polyploid evolution. The variation patterns were analysed at various geographic levels using molecular markers (plastid DNA and ITS of nrDNA), cytolo

Experiments with Haptic Perception in a Robotic Hand
This paper describes a robotic hand, LUCS Haptic Hand I, that has been built as a first step in a project aiming at the study haptic perception. Grasping tests with the hand were done with different objects, and the signal patterns from the sensors were studied and analyzed. The results suggest that LUCS Haptic Hand I provides signal patterns that are possible to categorize. Certain higher-level p
