In this paper, we investigate channel estimation and signal detection for UWB communications. We first investigate channel estimation for UWB systems and then develop a minimum mean-square-error (MMSE) Rake receiver with joint timing and MMSE equalization. The key property of the estimator is that it uses sampling at UWB symbol rate (200Msamples/s), while estimating all relevant channel parameters
In the context of growing concerns over climate change and peak oil, biofuels for transport are attracting considerable support from the European Union (EU). However, the sustainability of biofuels is under increasing debate. Furthermore, the complexity of the biofuels industry (involving different resources and feedstock suppliers, different logistics providers and options, a range of technologie

The transmission properties of perforated perfectly conducting screens are of practical interest. The treatment of non-periodical structures by numerical tecniques, such as the method of moments, is very computer intensive. In this paper it is shown that using well adapted basis functions, the number of unknowns can be drastically reduced. Advantages and limitations of the method are discussed. Nu
This thesis explores the educational and methodological opportunities of the ‘not-yet-seen’. Departure is taken in the philosophy of Deleuze and Guattari, and in pivotal concepts that challenge the image of the stabile subject, chronological time and established dichotomies in general. The aim of the thesis is three folded. First, it aims to plug the philosophy of Deleuze and Guattari in with educ
Software development is a complex area and extensive practice and reflection is required in order to obtain a good understanding of the different tasks involved in going from idea to deliverable software. To help in providing this understanding, we have developed a team programming course based on extreme programming and a coaching course. We discuss how these courses affect the curriculum, the de
