This book focuses on practical computational electrodynamics, guiding the reader step-by-step through the modeling process from the initial "what question must the model answer?", through the setting up of a computer model, to post processing, validation and optimization. The book offers a realistic view of the capabilities and limits of current 3-D field simulators and how to apply this knowledge efficiently to EM analysis and design of RF applications in modern communication systems.

The 18th Tyrrhenian Workshop on digital communications is devoted to wi- less communications. In the last decade, wireless communications research boosted launching new standards and proposing new techniques for the - cess technology. We moved from the UTRA standard capable to transmit 0. 5bit/s/Hz to WLAN which is promising 2. 7bit/s/Hz. Now wireless c- munication systems are facing a ?ourishing of new proposal moving from multiple antennas at transmitter and receiver side (MIMO systems), to new powerfulForwardErrorCorrectionCodes,toadaptiveradioresourcemana- mentalgorithms. Thenewchallenge,however,isthemovetowardsmultimedia communications and IP technology. This move implies e?orts in several new aspects. First of all an open network, as IP is, imposes the necessity of a - cure network, to guarantee the privacy of the ongoing communications, avoid the use of the networks by unauthorized customers, avoid the misuses and the charge to third parties of the cost of the connection. Also, quality of service (QoS) of the communications is becoming a must in IP networks which are carrying services which need a guaranteed QoS as telephony, real time s- vices, etc. To get this new target some form of access control to the network must be setup. Recently, new form of communication networks has appeared to collect data for several applications (sensor networks, ad hoc networks, etc. ) and they need a connection with a backbone network which could be a wireless one with a larger range than the sensor or ad hoc networks.

The past decade has seen many advances in physical layer wireless communication theory and their implementation in wireless systems. This textbook takes a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multi-input, multi-output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from real wireless systems such as GSM, IS-95 (CDMA), IS-856 (1 x EV-DO), Flash OFDM and UWB (ultra-wideband). Particular emphasis is placed on the interplay between concepts and their implementation in real systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interest to practising engineers.
