With the operation of multiple radio links simultaneously in so-called soft handover situation, the link quality can significantly be improved. On the other hand, additional radio resources are necessary and distributed transmitters cause severe chan

One of the major challenges of the telecommunication community for the coming years will be to make multimedia services available to everyone, even to those who are in remote places. Broadband fixed wireless access (BFWA) is one of the best positione

The standardization of UMTS Terrestrial Radio Access (UTRA) in time division duplex (TDD) mode includes two different transmission modes at the physical layer. They differ in their chip rate and with it their bandwidth requirements and characteristic

UMTS Terrestrial Radio Access (UTRA) in time division duplex (TDD) mode is a combination of time division multiple access (TDMA) and code division multiple access (CDMA). Radio resources are disposed in the time as well as in the code domain and allo

This paper proposes a dynamic channel allocation strategy which takes advantage of switching point (SP) positioning, which is one of the features in the time division duplex (TDD) transmission mode. A switching point is where the transmission changes

A requirement for the performance evaluation of wireless systems by means of simulations is the knowledge of the path loss between transmitters and receivers. A new indoor path loss model for large-scale attenuation is proposed The multi-wall-and-flo

The TDD operation mode of UMTS allows highly dynamic and various configurations of the physical layer time frame. A key issue in developing access methodologies to the available spectrum is an optimal management of the rare radio resources. The appli

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 the Node B

The CDMA based UMTS transmission technology in which all users simultaneously share the same common range of spectrum gets rather affected by the system interference. The reduction of interference is therefore a key issue in the development of optima
