Multiple-input multiple-output (MIMO) is a mandatory feature of the Third Generation Partnership Project (3GPP) Long Term Evolution. This work investigates the performance of a low complexity channel estimator for LTE terminals with an emphasis on the 4 × 4 multiple antenna scheme. The presented work extends a promising low-complexity 2 × 2 MIMO channel estimator to the 4 × 4 MIMO case and evaluat
We report preliminary clinical results of autofluorescence imaging of malignant and benign skin lesions, using pulsed 355 nm laser excitation with synchronized detection. The novel synchronized detection system allows high signal-tonoise ratio to be achieved in the resulting autofluorescence signal, which may in turn produce high contrast images that improve diagnosis, even in the presence of ambi
Det är både tekniskt möjligt och ekonomiskt genomförbart att ställa om till ett CO 2-snålt samhälle2050. Men för att nå en sådan målsättning måste ett antal utmaningar och hinder övervinnas, vilketkan kräva både politisk styrning och institutionell förändring.Denna rapport fokuserar specifikt på samspelet mellan utvecklingen av godstransporter, logistik ochCO 2-utsläpp. Godstransporterna, som styr
Popular Abstract in Swedish Tillväxtfaktorer påverkar signaler mellan celler i hjärnan Människors hjärnor innehåller flera miljarder hjärnceller, vilka är förutsättningen för vårt beteende, våra känslor och våra tankar. Hjärncellerna bildar kontakter, synapser, med varandra. Genom dessa överförs signaler från en cell till en annan. Varje cell kontaktar en mängd andra celler, både sådana med liknanThe neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. Such plasticity is believed to be a cellular correlate for important processes like learning, but also for diseases, for

One of the major ways in which economic inequality can increase is when the development of wages of ordinary workers trail productivity and GDP growth, meaning that the increasing riches fall in the hand of other social groups (top employees, owners of land and capital). This paper investigates the relationship between wages and GDP in Denmark, Norway and Sweden from 1800 to 1910, using wage serie
The intense debate on continuity in child grammars has largely focused on the existence of Functional Categories (FCs) in early grammars despite differences in language use with adults (e.g., omissions, word order errors, lack of case marking). Simplified, the major theoretical explanations for these properties range from Maturational accounts (Radford 1990 and later) claiming an initial absence o
In this letter, we consider adaptive detection of a partly known signal corrupted by additive noise and strong interference with support that is only partly known. Assuming a homogeneous environment where the covariance matrix of the additive noise is the same for the primary and secondary data sets, although with the secondary data set also being affected by the interference, we allow for conic u
The inverse of the standard estimate of covariance matrix is frequently used in the portfolio theory to estimate the optimal portfolio weights. For this problem, the distribution of the linear transformation of the inverse is needed. We obtain this distribution in the case when the sample size is smaller than the dimension, the underlying covariance matrix is singular, and the vectors of returns a
This paper describes differences between the capacity of Swedish and Danish students to attain life quality. This was carried out by examining the level of competence in four different groups of Swedish and Danish students, and is based on the hypothesis that the possession of competence is a premise for the development of life quality. Competence means the ability to make sense in complex situati
The transport sector accounts for large proportions of greenhouse gas emissions and energy usage in Sweden, about 40% and 30%, respectively. Most of this, 93%, comes from road transports. There is, therefore, a strong political desire to reduce the use of fossil fuels in road transport. Several alternatives to fossil fuels have been discussed and, more recently, interest in electrically driven veh
