“…Meanwhile, the COST 2100 stochastic channel model in [19] produces the clusterwise CSI in terms of UT-level CSI for densely deployed UTs within the scope of the entire area by clustering. Nonetheless, conventional clustering techniques such as the KPowerMeans [20], the k-means [21] and the k-nearest neighbors [22], are not robust enough to imperfect UT-level CSI produced by the deep learning based technique. Fuzzy clustering such as UK-means in [23] and the conventional fuzzy c-means (FCM) clustering algorithm in [24], can be promising solution to combat the weakness of the imperfect UT-level CSI.…”

“…We adopt a typical mmWave indoor radio channel model based on extended Saleh–Valenzuela (eSV) channel model, and it is widely used in [2427]. Due to multipath clusters, this spatio‐temporal channel model can be expressed as right left right left right left right left right left right left0.278em 2em 0.278em 2em 0.278em 2em 0.278em 2em 0.278em 2em 0.278em3ptHi,s,k=γfalse∑cl,ryαcl,rybold-italicanormalr)(φcl,ryr,θcl,ryrbold-italicatφcl,ryt,θcl,rytnormalH. …”

“…Compared with the channels experienced by conventional multiple-input multipleoutput (MIMO) systems equipped with small-aperture antenna arrays, the channels for ELAA-based systems in millimeter-wave bands exhibit complex characteristics, e.g., significant spatial non-stationarity, which makes the statistical modeling more difficult [11][12][13]. In this paper, a propagation scenario where the Rx is equipped with an ELAA is considered; the analysis can be applied to the Tx side as well.…”
