From: Algorithm and hardware design of a 2D sorter-based K-best MIMO decoder
BER of 802.11ac system: 2D Sorter. K = 21, G=3, L1 = 4, L2 = 3, L3 = 1, 256-QAM, and SQRD were used in all cases. The terms ‘S4 FullSort’, ‘S4 NoSort’, ‘S32 FullSort’, and ‘S32 2D Sort’ denote that a full sorter is used in stage 4, no sorter is used in stage 4, full sorters are used in stages 3 and 2, and 2D sorters are used in stages 3 and 2, respectively.
