High energy coronal radiation in Black Hole X-Ray Binary sources is often absorbed by accretion disk winds and the resulting absorption signatures heavily depend on its ionizing spectral energy distribution (SED). Considering multiple ion absorbers in the wind (e.g. Fe XXV/XXVI, S XVI, Si XIV, Ca XX and Mg XII), we find that the relative strength of absorption among these ions in general sensitively depends on the shape of the SED. We calculate a series of absorption line spectra from radiative transfer process for 9 distinct SED. Furthermore, we simulate 50 ks XRISM/Resolve spectra for each SED. We then fit the spectra by two-parameter wind model (SED and wind density normalization) to examine whether or not absorption features imprinted by the wind can be uniquely mapped to the ionizing SED.
