The user selection method based on chordal distance is widely used in multiuser multiple‐input multiple‐output (MU‐MIMO) systems with block diagonalisation. It has throughput close to the capacity based method with low complexity. In this Letter, a user selection method with higher throughput and much lower complexity is proposed. To investigate the performance in a more practical channel scenario, 3D MIMO channels are used in simulations. Compared with existing user selection algorithms, the proposed method achieves good throughput performance and the lowest complexity order.
