Abstract
A fast joint sorting and reduction (FJSR) algorithm is proposed, which involves elementary column operations only, to assist the successive interference cancellation (SIC) detection for multiple-input multiple-output (MIMO) systems. Simulation results show that the FJSR-aided SIC detector achieves good error performance especially when the system scales up, yet requires only a few extra basis updates over the optimal-ordered SIC detector regardless of the system size. This suggests that FJSR is particularly advantageous to small-to-medium scale MIMO systems with strict delay constraints..
