通过数据辅助信道估计在带有DD-LMS的时域滤波器上进行MIMO频域滤波器更新，显示了低复杂度自适应32分路2×2的优点。结果表明，该方法具有良好的稳定性和收敛速度，且具有相同的容差。
Benefits of a low-complexity adaptive 32-tap 2×2 MIMO frequency-domain filter update by data-aided channel estimation over a time-domain filter with DD-LMS are shown. Superior stability and convergence speed is demonstrated with identical impairment tolerance.
