Abstract:

A novel Multiple-input Multiple-output (MIMO) detection scheme based on orthogonal experimental design (OED) is proposed in this paper. By exploiting the initial solutions given by linear detection and non-linear detection algorithms, a searching subspace is constructed to obtain additional performance gain. Exhaustive searching method is optimal in the subspace, but with quite high complexity. Then OED, which is widely used in chemical experiments and statistics, is applied to reduce the computational complexity. The minimal required complexity of OED-MIMO is only 6.25% needed but just with insignificantly performance lost compared with exhaustive method for the 8×8 MIMO system and 16-QAM modulation scheme. The proposed OED-MIMO scheme provides nearly 10 dB gain compared with MMSE and 5 dB gain with ZF-VBLAST.
