TLDR
Wideband mobile radio channel characteristics were measured in mountainous terrain in Switzerland to define parameter settings for a frequency-selective fading simulator with which the performance of adaptive equalizers for the Pan-European digital land mobile radio system is to be tested.Abstract:
Wideband mobile radio channel characteristics were measured in mountainous terrain in Switzerland. Based on more than 76000 impulse responses, measured with two different experimental set-ups, statistical results were evaluated for mean excess delay, delay spread, delay interval, and correlation distance. This data was used to define parameter settings for a frequency-selective fading simulator with which the performance of adaptive equalizers for the Pan-European digital land mobile radio system is to be tested. >read more

Site-specific propagation prediction for wireless in-building personal communication system design
TL;DR: Time delay comparison shows that the amplitudes of many significant multipath components are accurately predicted by this model, and the effective building material properties are derived for two dissimilar buildings based upon comparison of measured and predicted power delay profiles.

A physical mobile radio channel model
W.R. Braun,U. Dersch +1 more
TL;DR: A model is presented for the time- and frequency-selective outdoor mobile radio channel based on the physical process of wave propagation in a statistical fluctuating medium and the reduction of this complex scattering problem to a set of relations containing the pertinent statistics for conducting communications system analysis is developed.

A new path-gain/delay-spread propagation model for digital cellular channels
TL;DR: A compact statistical model for the joint distribution of path gain and delay spread within a cellular environment, which lends itself readily to Monte Carlo simulation and is useful for performance studies of cellular systems with bandwidths up to tens of kilohertz.

TL;DR: Analysis of the data suggests that, for directive terminal antennas, the delay profile can be modeled as having a "spike-plus-exponential" shape, i.e., a strong return at the lowest delay, plus a set of returns whose mean powers decay exponentially with delay.
