Abstract :
The use of alternative modulation to provide Enhanced Data rates for Global Evolution (EDGE) is currently being standardized for GSM by the European Telecommunications Standards Institute (ETSI), and is also adopted for IS-136 evolution by the Universal Wireless Communications Consortium (UWCC) in the USA. In this paper, the currently proposed radio interface for this concept and first link simulation results are presented. It is demonstrated that high-level modulation is feasible with an acceptable increase of complexity, and provides good performance, even if impacts like power amplifier nonlinearity, phase noise, frequency offset etc. are taken into account,
