“…The coherence bandwidth of the RC-Rayleigh channel can be adjusted to the same values as measured in industrial environments (Coder et al, 2010;Chen et al, 2011); i.e., the intrinsic channel can be tuned to emulate a particular environment by loading the RC, e.g., with absorbers (e.g., Schwab and Kürner, 2011;Coder et al, 2010;Chen et al, 2011;Rajamani et al, 2013;Cui et al, 2012;Cammin et al, 2017b). This allows us to omit an additional CE, if a Rayleigh channel is desired (e.g., Lötbäck et al, 2015).…”
