Abstract
A multiple-input-multiple-output (MIMO) wireless communication enhanced detection method and apparatus are proposed whereby quasi optimal link performance is achieved, at low complexity for MIMO systems including those of high dimension and those operating at very high SNR.
Claims18
A method comprising:
- receiving a signal vector at a MIMO communications system;
- traversing, by the MIMO communication system, a reception lattice two or more times to mark a plurality of lattice points of the reception lattice, wherein each traversal of the reception lattice marks a lattice point that is closer to the received signal vector than a candidate set of neighboring lattice points, wherein the candidate set of neighboring lattice points does not include any marked lattice points;
- selecting, by the MIMO communication system, a selected lattice point, from the marked lattice points, that is closest to the received signal vector;
- and
- decoding, by the MIMO communication system, the received signal vector using the selected lattice point.
