In this work we study the problem of constructing precoders for spatially multiplexed multiple-input multiple output (MIMO) channels with close to optimal minimum Euclidean distance. In order to exploit the full potential of such designs, an ML detector must be used. Our design takes the decoding complexity into account and constrain it to a reasonable level. For our simplest case, the ML detector

This paper provides a general framework for electromagnetic modeling, computation and measurements regarding the wave propagation characteristics of High-Voltage Direct Current (HVDC) power cables. The modeling is focused on very long (10 km or more) HVDC power cables and the relevant frequency range is therefore in the low-frequency regime of about 0-100 kHz. An exact dispersion relation is form

The study investigates the changing growth pattern of 69 European regions measured at NUTS-level 2 between 1980 and 2002 by addressing the hypothesis of capital accumulation versus technological change as sources of convergence or divergence. The paper adds to the existing regional growth and convergence literature in three respects. First, regional estimates of capital stocks are constructed from

Det här föredraget argumenterar att noggrant utformade översättningsövningar kan ha en alldeles speciell plats i språkundervisningen, i alla fall för studenter på hög nivå. Förutsättningen är att studenter och lärare delar samma modersmål eller att åtminstone alla i klassrummet har god kunskap i det som är de flesta studenters modersmål. Föredraget baseras på en longitudinell och experimentell emp

What is the situation in Indian agriculture today? What has happened to production and distribution of land since independence? What has happened after the liberalisation of the Indian economy in the 1990s?

The aim of this study is to examine the relationship between retailer brand (RB) market shares and consumer prices. Furthermore it investigates whether changes in category price and expenditure are due to changes in customer purchase patterns or changes in relative price levels (price gap) of RBs and national brands (NBs). Data from the market research company GfK's consumer household panel, compr

The project “Arson - a societal problem” has been running with funding from a number of players since 2008. The project consists of a number of sub-projects and the work presented in this report was conducted within the sub-project: "Technical- and risk-based methods to prevent and mitigate the consequences of arson". The goal and purpose of the project was to develop and evaluate technical system

The INTERA and ECHO projects were partly intended to create a critical mass of open and linked metadata descriptions of language resources, helping researchers to understand the benefits of an increased visibility of language resources in the Internet and motivating them to participate. The work was based on the new IMDI version 3.0.3 which is a result of experiences with the earlier versions and

Vissa myter är svårare att slå hål på än andra. Att man i affärslivet alltid måste börja med att ses IRL, I Riktiga Livet, är en av myterna. Och ja, det stämmer att IRL-möten ofta är trevligare. De kan erbjuda en mer rik och effektiv kommunikation, man kan visa engagemang genom att besöka någon och ibland krävs det att man är på plats. Men, i de allra flesta fall finns det idag ett virtuellt alter
