Abstract

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
