Statistical characterization of a partitioned indoor radio channel

The relationship between the behavior of radio wave propagation and building architecture in a small indoor environment is examined. A site was divided into three partitions on the basis of the number of walls between the transmitter and receiver. Wideband radio propagation measurements were performed in each partition. The data are analyzed to compare channel characteristics in the partitions. The comparisons include the root-mean-square (RMS) delay spread values and its short time variations, values of the distance-power law gradient, and the short time fluctuations of received power. The statistics of path arrivals and amplitudes, used for simulation of the measured channel profiles, are also analyzed and compared to the partitions. The simulation model parameters in a partition are described by mathematical fits and are related to the number of walls between transmitter and receiver
