This paper presents a new Hardware (HW) im- plementation proposal for Discrete Fourier Transform (DFT) based channel estimators. The presented algorithm uses the high time correlation property of the channel estimates to reduce the complexity and the power consumption by utilizing a lower number of bits for the FFT in the channel estimator, compared to a traditional approach. The idea is that the

The standard way of representing an epistemic state in formal philosophy is in terms of a set of sentences, corresponding to the agent's beliefs, and an ordering of those sentences, reflecting how well entrenched they are in the agent's epistemic state. We argue that this wide-spread representational view-a view that we identify as a "Quinean dogma" - is incapable of making certain crucial distinc
The LDC formalism for DIS can describe HERA structure functions, and also agrees well with CTEQ and MRST gluon distributions. It is also suitable for hadronic collisions, and provides a strong connection between ep and pp reactions. Some preliminary results are presented.
This paper reports on some preliminary results from the first stage of an interview survey, focusing on current practices and challenges in market-driven RE. The interviews are analysed based on the characteristics of market-driven RE presented in the literature. The interviews correspond largely with the literature. Identified discrepancies compared with the literature concerns the time-to-market
This paper addresses the antenna subset selection in multiple antenna systems with full diversity transmission, for both correlated and uncorrelated channels. To reduce the severe performance degradation of traditional selection/combining schemes, we propose to embed phase-shift-only operations in the RF chains before selection. The resulting system shows a significant advantage in utilizing the m
The key adaptive techniques are automatic tuning, gain scheduling and continuous adaptation. This paper describes how these techniques are used for industrial process control When implementing the ideas in products, it is particularly important to make the systems so that they can be used by ordinary plant personnel. Some ways to achieve this are discussed.
Popular Abstract in Swedish Denna avhandling tar sin utgångspunkt i frågor kring markförstörelse och minskad bördighet inom småskaligt jordbruk i Afrika söder om Sahara. Genom empirisk forskning bland småbrukare i Tororo i sydöstra Uganda pekar avhandlingen på olika former av kollektiva strategier på lokal nivå för att hantera förändrade försörjningsvillkor. I en ansats att samproducera kunskap meProceeding from land degradation and soil fertility decline in sub-Saharan African smallholder agriculture and drawing on empirical research with smallholder farmers in Tororo district in south-eastern Uganda (2010-2012), this thesis identifies local collective strategies in response to changing livelihood conditions. In an attempt to co-produce knowledge with a transformative potential, the thesi
