We consider designing demodulators for linear vector channels that use reduced-size trellis descriptions for the received signal. We assume an iterative receiver and use interference cancellation (IC) with soft-information provided by an outer decoder to mitigate the signal part that is not covered by a reduced-size trellis description. In order to reach a trellis description, a linear filter is a

We consider the potential for positioning with a system where antenna arrays are deployed as a large intelligent surface (LIS), which is a newly proposed concept beyond massive multi-input multi-output (MIMO) where future man-made structures are electronically active with integrated electronics and wireless communication making the entire environment "intelligent". In a first step, we derive Fishe

In this paper, we consider the potential of data-transmission in a system with a massive number of radiating and sensing elements, thought of as a contiguous surface of electromagnetically active material. We refer to this as a Large Intelligent Surface (LIS). The "LIS" is a newly proposed concept, which conceptually goes beyond contemporary massive MIMO technology, and arises from our vision of a

Despite early reports and the contemporary consensus on microsaccades as purely binocular phenomena, recent work has proposed not only the existence of monocular microsaccades, but also that they serve functional purposes. We take a critical look at the detection of monocular microsaccades from a signal perspective, using raw data and a state-of-the-art, video-based eye tracker. In agreement with

Previous studies have proposed that people can use visual cues such as the instantaneous direction (i.e., heading) or future path trajectory of travel specified by optic flow or target visual direction in egocentric space to steer or walk toward a goal. In the current study, we examined what visual cues people use to guide their goal-oriented locomotion and whether their reliance on such visual cu

This dissertation looks into surrogate safety measures and behavioural indicators that are collected through site-based observations. Surrogate safety measures are defined as measurements that are used to describe the relationship between two road users in a traffic event for the purpose of quantifying the crash probability and/or the potential crash severity in a meaningful way. The main goal of

Jordbruket har en stor miljöbelastning, men är också alltmer centralt för att finna lösningar på hållbarhetsproblem. Ett angreppssätt för ökad hållbarhet är politisk styrning och reglering. I avhandlingen analyserar jag några frivilliga marknadsbaserade regleringar: certifiering och rapportering. Detta är regleringar som involverar företag och konsumenter. Jag har undersökt hur några sådana initiaAgricultural businesses contribute to sustainability problems, but they are also increasingly central to the effort to develop solutions. One way of moving toward sustainability is through regulatory governance. In this thesis, I analyze a tool of regulatory governance called voluntary market-based regulatory initiatives. Specifically, I investigate two types of initiatives, certification and disc

Under conditions of semiocapitalism – wherein signs, rather than goods or even services, are the main output of abstract production – the architectural “project” has become the primary technology for organizing architectural labor. The project, we argue, also acts as a capture device capable of linking economic production and the production of subjectivity, facilitating both the reproduction of (a
