where i is an i-th vector of ES channel matrix ES, and βi is a threshold parameter determined based on a nulling level in the direction of the ES, and
wherein, for l=1 and normalized ∥1∥=1, an optimal  can be obtained as a right singular vector from SVD of UE, such that the right singular vector is a strongest vector that satisfies |iH|≤βi.
