Although the K-best algorithm is well-known as an efficient suboptimal version of the maximum likelihood detection (MLD), its complexity is still significantly affected by the constellation size W. Especially, its sorting task is known as the major bottleneck. In this paper we propose a two dimensional (2D) sorter-based K-best algorithm, whose complexity is… CONTINUE READING
