ASYMPTOTIC PROPERTY STUDY OF THE LEAST SQUARE ESTIMATES OF 2-D EXPONENTIAL SIGNALS VIA COMPLEX SIGNAL PROCESSING APPROACH

  • 摘要: 二維復(fù)指數(shù)信號廣泛應(yīng)用于許多實際場合,本文利用復(fù)隨機(jī)信號處理方法研究其最小二乘估計的漸近性能。D.Kundu等人(1996)是將復(fù)信號表為實部和虛部來討論的,因而非常繁瑣。用復(fù)信號處理方法將可使討論大大簡化。
    Abstract: By use of the approach of complex random signal processing, the asymptotic statistical properties of the least square estimates of 2-D exponential signals are studied. In doing so it is found that the representation is considerably more intuitive, and is analytically more tractable.
