We show that measurements of time-varying mobile radio channels obtained with uncalibrated
correlative channel sounders are affected by four different types of systematic errors (…

The European standard for the terrestrial digital video broadcasting, DVB-T, is primarily
designated to the stationary and portable reception of video services. In most European …

In this paper the polarization properties of the indoor radio channel are investigated. By
means of a ray tracing approach different combinations of polarization of antennas at the …

Intelligent antennas offer the possibility of greatly increasing the capacity of cellular mobile
radio systems. We give a comprehensive overview of the literature concerning model …

Measurements are carried out at the protocol interface between base transceiver station
and base station controller unit for optimization of the base station subsystem in an existing …

Due to the increasing interest in mobile multimedia applications requiring high bandwidths,
channel models need to be derived which represent properly broadband mobile radio …

Describes efficient methods, which are able to predict the expected speech quality by deriving
a measurement from the GSM standard measurement RXQUAL (coded bit error rate) and …

Pilot symbol assisted modulation (PSAM) of the subcarriers of an OFDM system seems to
be very attractive for high data rate radio systems. It is used, or will be in the near future, in …

The assignment of resources to cells of a cellular mobile radio network is an important task
in design and operation of a network. In practice, the number of resource units that are …

Future mobile radio networks are expected to witness increasing capacity demands. At the
same time, operational expenditures are expected to rise due to increasing network …
