The conference-series called in recent years IST Mobile and Wireless Communication Summit grew during its 16 years of history to a major conference being very likely the most important in its subject in Europe. The original aim of the Summits was to report on the progress of European Union-sponsored R&D projects; however, they became general open call conferences, with covered subjects much wider than these projects. Its 16th edition having been held 1–5 July 2007 in Budapest Hungary was similar to its predecessors, in subject, in niveau and in the number of participants. This book is a selection of the topics covered in the conference. Authors of about 15% of the presented papers were invited to contribute to the book, with extended versions of their papers. The result is the present book. (Interestingly enough, the final selection contains, by chance, 10 chapters strictly related to EU projects and 10 being independent from these.) niques. Chapter 2 (Sigdel and Krzymien) proposes and investigates two novel algorithms for scheduling and antenna selection in Orthogonal SDMA (Space Division Multiple Access) multiuser MIMO downlink. In Chapter 3 Yu and Alexiou, after briefly describing spatial multiplexing and diversity performance of MIMO transmission investigate the effect of various errors. In Chapter 4 (by Marsch and Fettweiss) various aspects and advantages of multi-base-station cooperation are discussed.
Two chapters of Part II deal with access. Chapter 5 written by Kovács and Vidács deals with the resource allocation (RA) problem from a techno-economic point of view. They propose a novel pricing method which enhances tolerance of users toward other users of the network. Chapter 6 (by Maciel and Klein) investigates and compares two approaches of RA in the case of Orthogonal SDMA-FDMA; with The book, divided into six parts comprises twenty chapters. The four chapters of Part I deal with problems of the physical layer. Chapter 1 written by Bauch and Kusume investigates high performance (multidimensional) zigzag codes; the main problem here is interleaver design; attempt of optimization is made. Next two chapters deal with MIMO their proposed (sub-optimal) method the targeted maximizing of the weighted capacity is fairly well achieved.
