This contribution proposes a concept for specifying properties of time-variant propagation channels and their impact on modulated signals. The basic idea is to measure the modulating properties of the channel in an intermediate frequency band where necessary numerical calculations can effectively be performed with drastically reduced demands on calculation time and memory. A typical scenario for scatterers...
The key aspect of reverberation chambers (RC) is the statistic behavior of the field inside including the influence of the moving, respectively rotating mode stirrer. By means of a vectorial channel sounder presented in this contribution the dynamic influences of the stirrer are investigated with respect to its mechanical relaxation time and its efficiency. Additionally, the ability of vectorial channel...
