Abstract :
In this paper, a new MIMO equalizer referred to as weighted interference-cancellation equalizer (WICE) is proposed. WICE is a novel multistage equalizer that is similar to the MIMO decision-feedback equalization (DFE) in structure, but has better performance and is more immune to error propagation. WICE can be applied to both the single-carrier and spread-spectrum multiuser systems. Simulation results show that the proposed algorithm significantly outperforms the conventional MIMO signal processors in both the single-carrier and spread-spectrum scenarios.
