This paper discusses design and measurements of a flexible Viterbi decoder fabricated in 130-nm digital CMOS. Flexibility was incorporated by providing various code rates and modulation schemes to adjust to varying channel conditions. Based on previous trade-off studies, flexible building blocks were carefully designed to cause as little area penalty as possible. The chip runs down to a minimal co

This paper presents examples of different aspects of design in a disability context with the aim of revealing some of its fundamentals. It particularly emphasizes situated aspects of research: the need for being there, with the users in their daily lives – where the action is.

Due to the fine delay resolution of typical ultra wideband (UWB) systems, Rake receivers need to combine samples from a large number of multipath components (MPCs) in order to collect sufficient signal energy for reliable decisions. In addition, these samples need to be combined optimally in order to minimize bit error probability. The optimal linear minimum mean square error (MMSE) combining sche

"We know and can do much more than we thought we could!" Perhaps this is what is most clearly revealed by the participants in Pacemaking Jönköping. The process, final report and the project's continuation comprise living proof that people in Sweden in 2

Surface-associated plasmin(ogen) may contribute to the invasive properties of various cells. Analysis of plasmin(ogen)-binding surface proteins is therefore of interest. The N-terminal variable regions of M-like (ML) proteins from five different group A streptococcal serotypes (33, 41, 52, 53 and 56) exhibiting the plasminogen-binding phenotype were cloned and expressed in Escherichia coli. The re

Den ekonomiska krisen borde öka benägenheten att ansluta sig till facket, men medlemmarna sviker och störst är raset hos hotell- och restauranganställda. Anders Kjellberg är docent i sociologi och forskar vid Lunds universitet kring facklig anslutning. - Mellan 2006 och 2008 sjönk fackanslutningen från 77% till 71%. Hade det inte varit för lågkonjunkturen hade raset varit ännu större, säger Kjellb

An increasingly competitive environment, technological advancements and globalisation are a few of the factors placing higher demands on today’s company activities, e.g. development, production and distribution processes. Company activities have hereby become a complex system, even more so if one company is seen as part of a network of companies. The aim of this article is to present and elaborate
