4.1 Uplink and Downlink MIMO-NOMA with Simultaneous Triangularization

This errata is for the publication [12], which is also available on arXiv here: https://arxiv.org/abs/2006.06471. In the proof of Theorem $2$ in Appendix A.2, the second sentence must read “Let $𝑲\in {ℂ}^{N\times M}$ denote the matrix containing a basis for the null space of ” That is, the Hermitian transpose is required for the augmented matrix rather than the individual matrices with null-space bases.

See Section 1.3.2 for the complete theorem and proof along with MATLAB reference code.
