Power delay profile analysis and modeling of industrial indoor channels
MetadataShow full item record
In this paper, power delay profile (PDP) measurements of three different industrial indoor environments are presented. The measurements were performed in the frequency range of 800 MHz to 2.7 GHz using a vector network analyzer (VNA) and the virtual antenna array method. Dense multipath scattering with multipath components arriving in clusters was observed. This is due to the abundance of highly reflective scatterers present in the measured industrial environments. The measurement results reveal two different shapes of PDP, neither of which fully fits the well known Saleh-Valenzuela (S-V) model or power-law model. Thus, modifications were made on the conventional S-V model and power-law model to better represent the measurement results. Furthermore, Weibull distribution was found to fit the measured small-scale fading.
