On the second order power spectral statistics of wideband indoor microwave channels

On the Physical Interpretation of the Saleh–Valenzuela Model and the Definition of Its Power Delay Profiles

“…The corresponding analytical results are given by ( 14) and ( 20)- (23), where the averaged properties per cluster can be found by substituting (7) in ( 15) and ( 24)-( 27 As a numerical example, the variables that were generated in the previous subsection were substituted in the equations above, (14), and ( 20) through (23) (i.e., no new simulation was run). The resulting normalized PDP and FCF are plotted in Figs.…”

“…The expected PDP and other channel properties can then be found by substituting the results of the previous subsection in ( 20) through (23), and averaging over the cluster arrival delays…”

“…Note that the FCF is fundamentally different from the second-order power spectral characteristics that are derived in[22] and[23]; the latter concern the (normalized) autocovariance function of the power transfer , whereas the FCF is the autocorrelation of the transfer function itself. Relating them is far from straightforward due to the complicated underlying statistics of .…”
