Statistical Channel Models for Millimeter-Wave Wireless Data Centers

Abstract

This paper presents a set of statistical channel models based on 60 GHz radio measurements in a server room. The channel models are developed for possible use-cases, corresponding to potential deployment scenarios in wireless data centers (WDCs). A simple parametric channel model is used to model both the deterministic and stochastic channel parameters in the delay domain, within the 57-64 GHz unlicensed band. A simulation framework is accordingly provided to generate channel realizations for WDC use cases. The accuracy of the simulation framework is verified using the delay spread as a validation metric. The reported models are useful for practical system design and evaluation of WDCs millimeter-wave systems.

“…where |h n | is the magnitude of the n th tap of of the channel impulse response. The PDP taps are subject to a power level threshold [(P LoS|dB − 30)] on the output of the peak detection method used in [3]. The channel capacity for a GI based receiver is given by:…”

“…In our previous work [2], we investigated the propagation channel characteristics for WDC deployment scenarios by radio channel measurements using a vector network analyzer (VNA) based channel sounder. Subsequently, we developed statistical channel models to express both the deterministic and stochastic channel parameters in the delay domain [3]. In this letter, the channel capacity is evaluated based on the modeled and measured 60 GHz radio channel in a productivity server room.…”
