Statistical characterisation of a partitioned indoor radio channel

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