TLDR
The requirements for third-generation cellular mobile radio systems such as Universal Mobile Telecommunications System (UMTS) and Future Public Land Mobile Telecommunications system (FPLMTS), which has been named International Mobile Telecommunications after the year 2000 (IMT-2000) are presented concisely.Abstract:
In Europe, the challenge of the design of third-generation cellular mobile radio systems has been taken numerous research and development activities in this field have been started. The authors try to give an overview of the European activities in this field. The article is organized in two parts. In the first part, the requirements for third-generation cellular mobile radio systems such as Universal Mobile Telecommunications System (UMTS) and Future Public Land Mobile Telecommunications System (FPLMTS), which has been named International Mobile Telecommunications after the year 2000 (IMT-2000) are presented concisely. Also, the importance and challenge of the multiple access design for such third-generation cellular mobile radio systems is explained. In the second part, numerous European research activities with focus on the multiple access design for third-generation cellular mobile radio systems are reviewed.read more

Performance evaluation of a novel M-detector for coherent receiver antenna diversity in a GSM-type mobile radio system
TL;DR: The M-detector is extended to CRAD in the case of maximal-ratio combining (MRC), equal-gain combining (EGC), and selection combining (SC), and its performance in GSM type mobile radio systems is studied by simulations using the radio channel models rural area (RA), typical urban (TU), and bad urban (BU) specified by COST 207.

Optimal and adaptive FIR filter receivers for DS-CDMA
TL;DR: The choice of an FIR filter enables the authors to calculate optimal filter in the presence of MAI and additive noise using Wiener filter theory and to describe a method for extending the optimisation process to include the multipath cellular channel.
