An integrative overview of the open literature's empirical data on the indoor radiowave propagation channel's temporal properties.

摘要

This paper offers a comprehensive and integrative overview of empirical data available from the open literature on various temporal properties of the indoor radiowave communication channel. These data were originally presented in about 80 papers in various journals, conferences, and books. The indoor radiowave propagation channel's statistical properties depend on the physical environment (e.g., the floor layout, the construction materials, furnishing's locations and electromagnetic properties) and the transmitted signal's carrier-frequency, the transmitter's location, the receiver's location, the receiver's detection amplitude threshold. Overviewed in this paper are the multipaths' amplitude versus arrival delay, the probability of multipath arrival versus arrival delay, the multipath amplitude's temporal correlation, the power delay profile and associated time dispersion parameters (e.g., the RMS delay spread and the mean delay), the coherence bandwidth, and empirically "tuned" tapped-delay-line models.
