The Global System for Mobile Communication met with wide acceptance in 1993. Its technical conception has significant advantages over the first generation of cellular systems. Digital European Cordless Telecommunications will provide similar advantages. In Europe, the second generation of wireless communication is established and a Universal Mobile Telecommunications System is currently being conceived. All this leads to a natural subdivision of current research into four categories: new and improved usage of existing standards, signal processing algorithms that are simpler or closer to the optimum, forther development of existing systems, and work that will ultimately lead to new system proposals. This volume presents the proceedings of a seminar at which all these categories were covered.
