Doppler Spread Estimation In Mobile Fading Channels, Hong Zhang
Doppler Spread Estimation In Mobile Fading Channels, Hong Zhang
Dissertations
The Doppler spread, or equivalently, the mobile speed, is a measure of the spectral dispersion of a mobile fading channel. Accurate estimation of the mobile speed is important in wireless mobile applications which require such as knowledge of the rate of channel variations. In this dissertation, first the performance of classical crossing- and covariance-based speed estimators is studied. Next, the problem of mobile speed estimation using diversity combining is investigated. Then, a nonparametric estimation technique is proposed that is robust to different channel variations. Finally, cyclostationarity-based speed estimators which can be applied either blindly or with the aid of pilot …

Using Gis To Assess Ireland's Knowledge Economy And Its Readiness For Knowledge Based Activity, Niall Mcguinness
Using Gis To Assess Ireland's Knowledge Economy And Its Readiness For Knowledge Based Activity, Niall Mcguinness
Dissertations
The attractiveness of emerging low wages economics to primary industries such as manufacturing and production is forcing many western economies to transition to knowledge economies. In the absence of many forms of primary industry lost to low wage economies, the European Union and its members are fast realising the importance of attracting knowledge based enterprise in order to maintain Europe’s economic climate. Ireland too has a stated aim to become a knowledge economy by the year 2010. This can be achieved by investing in higher education and attracting knowledge industry to the country. Ireland has made some progress to achieving …
Information Architecture For Irish Grocery Retailers Using Business Intelligence Tools, Patrick Doran
Information Architecture For Irish Grocery Retailers Using Business Intelligence Tools, Patrick Doran
Dissertations
Business Intelligence (BI) systems have a pivotal role to play in assisting retail management in the Irish grocery retail sector. The emergence of super chain stores and the increasing competition within this sector only increases their need for an effective and reliable Business Intelligence (BI) system. However, despite this growing need Business Intelligence (BI) systems as they are currently deployed and used are not supplying the various levels of management with the necessary information they require to make effective retail management decisions. The information and reports received from Business Intelligence (BI) systems lack structure, are missing important pieces of information …
Open Software To Innovation: The Critical Success Factors Of Massively Multiplayer Online Role Playing Games (Mmorpg) In China And Ireland., Wei Chen
Dissertations
This project investigates the factors leading to the success of China’s Massively Multiplayer Online Role Playing Games (MMORPG) market and gives an analysis of how Open source has contributed to these success factors. It then will look at how the use of open source is mirrored in Ireland’s market for example, the software sector to see if the same factors are apparent or there are indicators of these. Knowledge Management plays a very important role for fasten the innovation of Open source software development in China.
