Target-induced channel attenuation for the link ℓ5, identified by the antenna pair (u=2,v=2), and the by the sub-carrier f15. In a, the target is located at position K14, and in b, the corresponding CSI values are measured by both RX1 and RX2 receivers. In c, the target is located at position K28, while in d, the corresponding channel attenuation is measured by both RX1 and RX2
