TLDR
The rationale behind the development of the EDGE concept is given, the technology will provide significantly higher user bit rates and spectral efficiency, and performance is addressed by means of system simulations.Abstract:
Two of the major second-generation standards, GSM and TDMA/136, have built the foundation to offer a common global radio access for data services. Through use of a common physical layer, EDGE, both standards will have the same evolutionary path toward providing third-generation services. EDGE is currently subject to standardization in TIA TR45.3 and ETSI SMG, a process which will be finalized at the end of 1999. Compared to the existing data services in GSM and TDMA/136, EDGE will provide significantly higher user bit rates and spectral efficiency. EDGE can be introduced in these systems in a smooth way, using existing frequency plans of already deployed networks. This article gives the rationale behind the development of the EDGE concept, presents the EDGE technology, and addresses performance by means of system simulations.read more

TL;DR: 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.
