Resource allocation algorithms and power control for cellular systems
Multiband (or multi-carrier) CDMA is a promising approach to increasing the capacity of CDMA systems, while maintaining compatibility with existing systems. This paper surveys three different power control based resource allocation algorith...
An iterative multiuser detection receiver for 3GPP with antenna arrays: performance in terms of BER, cell size and capacity
This paper discusses the implementation of a very powerful but computationally efficient, iterative multi-user detector, intended for use as the base station physical layer receiver for wideband CDMA. This multiuser detector is unique in th...
Session establishment over satellite-UMTS
As part of the roll out of Universal Mobile Telecommunication Systems (UMTS), a satellite component has been identified, aiming at providing a seamless communication. Since an all IP architecture has been defined by the Third Generation Par...
IP header and signalling compression for 3G systems
IP header compression techniques have evolved to meet the challenges of cellular networks. The scope has also broadened. Solutions are being developed for voice traffic transport, SIP and protocols such as TCP, which covers the major traffi...
Multicasting in UMTS
Future third generation wireless network operators, such as those holding UMTS (Universal Mobile Telecommunications System) licenses will be able to deliver higher bandwidth content rich services over new infrastructure to end-users of inno...
Mobility management in mobile Internet
Efficient mobility management is essential for future communication networks due to the evident trend of increasingly mobile users. A number of mobility management schemes are introduced in the literature. However, there seem to be various ...
The effect of electrical and mechanical antenna down-tilting in UMTS networks
In an interference-limited CDMA system, network planning and the optimal installation of infrastructure components are important issues. This is not only to increase system capacity but also to allow for a smooth network operation. Whereas ...
