Lattice Reduction-Based List Detection
Since most low-complexity suboptimal MIMO detectors could not exploit a full receive diversity gain , the LR-based MIMO detectors are developed to provide a full receive diversity gain with low computational complexity [56, 69, 70]. The LR-based MIMO detector is first discussed in , then more LR-based MIMO detectors are proposed in . It has been shown that the LR-based MIMO detector using the MMSE-SIC approach, namely the LR-based MMSE-SIC detector, approaches the ML performance. An overview of LR-based detection can be found in  and a soft-decision with the detection is discussed in .
