Joint DL and UL Channel Estimation for Millimeter Wave MIMO Systems Using Tensor Modeling

Algorithm 2

Pseudocode of the LS-KRF receiver.

(1)	Apply the operator in the i-th column of (30) to obtain the rank 1 matrix ;
(2)	Compute the SVD . Then, obtain the estimates for the i-th columns of and as:
	where and are the first left and right singular vectors of and , respectively, and is the largest singular value;
(3)	Repeat steps 1-2 for all columns of (30).
