Abstract:
A computationally efficient soft-output detector with lattice-reduction(LR)for the multiple-input multiple-output(MIMO) systems is proposed.In the proposed scheme,the sorted QR de- composition is applied on the lattice-reduced equivalent channel to obtain the tree structure.With the aid of the boundary control, the stack algorithm searches a small part of the whole search tree to generate a handful of candidate lists in the reduced lattice. The proposed soft-output algorithm achieves near-optimal perfor- mance in a coded MIMO system and the associated computational complexity is substantially lower than that of previously proposed methods.
