Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem

The second method, Decision directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

Politiska beslutskedjors uppkomst och utveckling - En fallstudie av ett politiskt beslutsfenomen

This study aims to investigate the origin and the development of a certain type of decision phenomena, namely political decision chains. A political decision chain is defined as a seemingly rational decision being made, that is reverted through a new decision and this for other reasons than the original decision being regarded as having fulfilled its intended purpose. The essay attempts to explain the occurrence of these decision chains through a case study in order to thoroughly examine the complexities that surround political decisions overall. The essay concludes that uncontrollable factors and chance to a large extent affect the origin of these chains, allowing actors to change the political agenda according to their preferences. The relative weighting of these factors that is made by the actors, which exist within the decision chain, makes them underestimate the relative power of other actors that may have different preferences.

Investering i tidig läkemedelsutveckling. En studie om hur man tar beslut under osäkerhet.

This case study aims to explore how decision making is performed under circumstances characterised by high uncertainty. We have identified and interviewed two types of organisations dealing with investments in pharmaceutical drug development, a business characterised by high uncertainty. We have found that the two types of organisations we have interviewed display different decision making behaviour evaluating the same type of investment. Further we have explained these differences in decision making behaviour by using relevant decision making theories. This study has showed that different forms of decision making are appropriate depending on the conditions facing the decision maker..

Stockholms Lokaltrafik, SL : kundinvolvering i trygghetspolicyn

Society has seen a tremendous increase in threats, violence and especially unprovoked violence perpetrated by youths. Violence and more seriously unprovoked violence has become a major problem for many service corporations as it gives them bad image and reputation. Corporate Social Responsibility CSR encourages many companies to engage in social activities as they realize that the company is part of the society and the environment. What affects society may sooner or later affect the corporate. For any business to prosper and create a long-term relationship with its customers, it needs a safe environment both for the customers and staff.Feedback from customers and staff is survival and these two (customer and staff) are the most vital assets any firm could have.

A Strategic Decision-Making Model for Supply Chain - A Void to be Filled

Many researchers emphasize the increasing strategic importance of supply chain management, but there is still a lack of concrete guidance for managers faced with strategic decisions in supply chain. Within decision-making theories, the rational decision-making model is the most commonly used. This because of its suitable foundation, enabling a structure to the complex decision process. The rational decision-making model is today not developed to include the aspects of strategic decision-making made in supply chain. The purpose of this research is to adjust a structured rational decision-making model, making it applicable for strategic decision-making in supply chain.

Det politiska beslutsfattandet under Tsunamikatastrofen: Vilken roll spelade media?

Att skapa konsensus- En fallstudie av beslutsprocessen inom kommunsamarbetet NOSAM

The purpose of this thesis is to analyze the construction of consensus in commune-collaborations. By a review of written material combined with elite interviews we have been able to follow the decision-making and the forming of consensus, in a commune-collaboration called NOSAM, in which they have decided to use consensus as a decision method. The thesis is based on a case study and we have decided to follow a specific issue that has been discussed for some time.We have created an instrument based on the ideal of deliberative democracy, through which we have been able to examine whether the decision-making in NOSAM can be described as a deliberative process or if consensus is formed by other incentives.The study shows that the decision-making in NOSAM cannot be described as a deliberative process, although there are some elements of deliberation. Consensus is formed in a proposition drawn up by the officials for the commune-representatives to agree on. Afterwards, the decision has to be brought up in each commune before reaching a final decision in NOSAM.Our opinion is that having consensus as the decision method leads to difficulties when deciding on bigger issues..

?Ett beslut taget med hjärtat eller hjärnan??  : En beskrivande studie om donationsbeslut och processen bakom.

Throughout the years more and more charitable organisations have appeared and the competition between them has increased. This has forced the charities to use more marketing strategies in their work in order to strengthen their competitiveness. Research in philanthropy in terms of economy and marketing has been neglected in Sweden and the research that is done today is mainly focused on why individuals donate to charity. A donation, according to the writers of this thesis, has been seen as an economical activity and can therefore be explained and understood through economical models and theories. This thesis aims to see how a contributor to charity makes the decision to donate money, consequently see how the donation decision process actually works from a theoretical model of a buying decision process from marketing literature. The purpose of this thesis is therefore to from a buying decision process concerning products describe the donation decision process for contributors to charity. By achieving this purpose the writers aim to compare if a donation decision process go through certain steps similar to a buying decision process.

Investeringsbedömningsprocessen för strategiska investeringar - en fallstudie av NordiCorp

The aim of this study is to examine the investment decision process for investments that arise due to strategic changes and are of strategic importance to the company. At the foundation of this study is the previous research in this area, done by King (1975) and Bower (1970), which examines the investment process on a more generic level. At the core is the investment decision process pertaining to Projekt X, an investment performed by NordiCorp. Having conducted a case study including six interviews with employees from various parts of the organization, combined with a large number of internal documents, the process regarding the investment decision was carefully illuminated. The results show that in many regards, this process follows the more generic investment process.
