摘要：

针对多入多出(MIMO)系统中的最大多谱勒频移估计，运用单因素试验的方差分析法对多组估计值进行建模和假设检验，提出了基于最大距离判决和置换均值原则的野值剔除方法. 研究表明，该方法可以有效检测并删除估计值中的不合理数据，提高MIMO系统中最大多普勒频移估计的精度.

关键词: 多入多出系统, 最大多普勒频移估计, 单因素试验的方差分析, 野值剔除

Abstract:

For maximum Doppler shift estimation in multi-input multi-output (MIMO) systems, the single-factor analysis of variance was applied to establish mathematical model and perform hypotheses testing for estimated values. Furthermore, a novel scheme for illegal data elimination was proposed based on the principle of maximum distance judgment and mean value replacement. Theoretical analysis and simulation results proved that the proposed scheme could detect and eliminate illegal data effectively and improve the accuracy of maximum Doppler shift estimation in MIMO systems.

Key words: multi-input multi-output systems, maximum Doppler shift estimation, single-factor analysis of variance, illegal data elimination
