Abstract
Lattice reduction (LR) has been researched a lot in conjunction with ordered successive interference cancellation (OSIC), contributing large enhancement of the performance with relatively small complexity. However, the performance gap between the LR-aided OSIC (LR-OSIC) and maximum likelihood (ML) still exists. This paper suggests LR-aided allordering successive interference cancellation (LR-AOSIC) as an optimum successive interference cancellation (SIC) detector showing near-ML performance almost unaffected by channel correlation and modulation order. In addition, LR-OSIC using modified local search algorithm (LR-MLS-OSIC) is also proposed as a sub-optimum SIC detector to reduce the complexity of LR-AOSIC affordably, nearly maintaining the performance. © 2015 IEEE.
