An approximate spatial correlation model for clustered multiple-input multiple-output (MIMO)
channels is proposed in this paper. The two ingredients for the model are an approximation …

In the context of the evolution towards 3rd Generation (3G) mobile radio networks, packet
switched data services like the General Packet Radio Service (GPRS) and the Enhanced …

Due to the explosive global growth in the number of mobile subscribers, as well as the
growth predicted in the mobile data segment, the need for improved spectrum efficiency on …

In this article, the performance and capacity gain achievable with quality of service (QoS)
management in packet switched radio networks based on the General Packet Radio Service …

This paper presents a method to model the bit error rate in GSM, taking as inputs the carrier
to interference ratio and the speed. The procedure is based on a characterisation of the bit …

This paper investigates a link adaptation algorithm based on channel quality heuristics,
which are extracted from the GSM transmission chain at the output of the equaliser. The aim …

The spaced frequency correlation affects the frequency diversity gain in frequency hopping
(FH) GSM systems. However, GSM link level simulations have not taken this into account. In …

This paper, based on the PALIO project, deals with an information tourist service accessible
through mobile phones by means of the Wireless Application Protocol (WAP). We have …

We discuss the results of recently published analytical concepts for the performance
evaluation of packet-switched mobile radio networks (see Vornefeld, U., Proc. European …

In this paper, the Wireless Application Protocol (WAP) as one application of mobile data
services is examined with the aim to give guidelines for the dimensioning of next generation …
