Описание: When joining Siemens in 2001, I also extended my research interest towards radio net work planning methodologies. This area of research brought together my personal interest in mobile communications and in the design of ef?cient algorithms and data structures. Between 2001 and 2003, I participated in the EU project Momentum, which was target ing the performance evaluation and optimization of UMTS radio networks. In this project my main focus was on Monte Carlo snapshot techniques, shortly after I broadened my research scope towards network optimization techniques. Both constitute the basis of this thesis. Later I got the chance to bring in the ideas and methods of my thesis into a Siemens internal planning and optimization tool, the development of which I guided over the last two years. First of all I would like to thank Professor Dr. Carmelita Gorg for supervising this thesis, for her guidance, and her encouragement. I very much appreciate that she although I, as an external Ph. D. student, was not part of her department at the University of Bremen was always very open for discussions and provided me with a large amount of useful suggestions over the past years. I without a doubt greatly bene?ted from this, both in my scienti?c work and personally. I am also deeply grateful for the comments and suggestions by Professor Dr. Thomas Kurner, who is also the second examiner of this thesis."

Описание: Written by leading experts in the field, the first edition of WCDMA for UMTS quickly became established as the best-selling and most highly respected book on the air interface of 3G cellular systems. Fully revised and updated, the fourth edition now covers the key features of 3GPP Release 7 ensuring its position as the leading principal resource in this constantly progressing area. The fourth edition provides a deep understanding of the WCDMA air interface, its capabilities and its optimal usage - the key to success in the UMTS business, making this practical approach highly accessible to operators, network and terminal manufacturers, service providers, university students and frequency regulators. The existing chapters have also been updated as follows; HSDPA chapter now with Release 7 updates including Multiple input multiple output (MIMO) and VoIP optimization; UMTS services and application has been updated and; Iub transport optimization for Release99 and HSDPA/HSUPA has been presented
Описание: Wireless Local Loop (WLL) is widely recognized as an economically viable technology for provision of telecommunication services to subscribers. This book covers the following topics: Introduction to WLL systems; Fundamentals of Radio Systems; Key cellular and cordless technologies; and WLL systems design system components and interfaces.
Описание: Quality Function Deployment (QFD) is a method for satisfying customers by translating their demands into design targets and quality assurance points. For a thorough "how-to" on the implementation of QFD, we went directly to the source -- Yoji Akao, the creator of QFD and one of the foremost leaders of the Japanese Total Quality Control movement. In this unprecedented book he explains the concepts and methods of this remarkable systems engineering approach. Filled with case studies, detailed charts, and over 100 diagrams, this book is a complete reference tool for QFD implementation. It includes- * Use of the demanded quality deployment chart. * Using and promoting quality charts. * Using quality control process charts: QFD at the pre-production. * Quality deployment and reliability deployment. * Quality development in the construction industry. * QFD for the service industry. * QFD for software development.
