Generation of Rayleigh/Rician Fading Channels With Variable RMS Delay by Changing Boundary Conditions of the Reverberation Chamber

This letter presents the properties of the generated Rayleigh/Rician fading channels in the reverberation chamber (RC) experimentally. Radio propagation channels that undergo multipath fading phenomena can be characterized by power delay profiles (PDPs), delay spreads, and statistical distributions of the received power. The RC under the conventional configuration for electromagnetic compatibility/electromagnetic interference (EMC/EMI) evaluations has Rayleigh distribution because there are no direct paths between the TX and RX antennas. Most of the transmitted signals arrive at the RX part through multiple reflection paths. By changing the boundary conditions and the position of the TX antenna, Rayleigh/Rician fading channels with variable root-mean-square (RMS) delay spread can be generated in the RC considering K-factor simultaneously.
