  • Multiple-input multiple-output signal detectors based on relaxed lattice reduction
    Patent number: 8611450
    Abstract: System and methodologies for reduced-complexity signal detection and decoding in a wireless communication system are provided herein. Systems and methodologies presented herein can utilize a relaxed form of the Lenstra-Lenstra-Lovasz (LLL) lattice reduction algorithm to reduce the complexity of lattice reduction operations in the context of MIMO detection. Additional systems and methodologies presented herein can apply lattice reduction in the context of a maximum likelihood (ML) detector for spherical or elliptical lattice space-time (LAST) codes.
    Type: Grant

  • LATTICE-REDUCTION-AIDED MIMO DETECTORS
    Publication number: 20090196360
    Abstract: A Lenstra-Lenstra-Lovász (LLL)-based technique is utilized to reduce the complexity of a MIMO detector. Basis vectors can be pre-sorted, such as by V-BLAST ordering or sorted-QR ordering, prior to applying Gram-Schmidt Orthogonalization (GSO) to further improve performance. Alternatively, a joint sorting and LLL reduction (JSAR) technique can be utilized such that after each reduction step, a vector remaining to be reduced can be selected that will minimize the overall complexity. The JSAR technique can be applied on real or complex lattice bases. LLL reduction can be stopped after a predetermined threshold is exceeded.
