- W2950894975 abstract "Ultra-Reliable Communication (URC) is one of the distinctive features of the upcoming 5G wireless communication. The level of reliability, going down to packet error rates (PER) of $10^{-9}$, should be sufficiently convincing in order to remove cables in an industrial setting or provide remote control of robots with mission-critical function. In this paper we present elements of physical and statistical modeling of the wireless channel that are relevant for characterization of the lower tail of the channel Cumulative Distribution Function (CDF). There are channel models, such as Two-Wave with Diffuse Power (TWDP) or Suzuki, where finding the full CDF is not tractable. We show that, for a wide range of channel models, the outage probability at URC levels can be approximated by a simple expression, whose exponent depends on the actual channel model. Furthermore, it is seen that the two-wave model leads to pessimistic predictions of the fading in the region of ultra-reliable communications, while the CDFs of models that contain diffuse components have slopes that correspond to the slope of a Rayleigh fading. We provide analysis of the receive antenna diversity schemes for URC-relevant statistics and obtain a new expression for Maximum Ratio Combining (MRC) in Weibull channels." @default.
