  1. Starting with the equivalence condition of admissibility, this paper discusses respectively the linear biased estimate of the regression coefficient of thee models : the g - m linear regression model, the multivariate linear regression and the mixed - effect coefficient linear model

    本文以可容許性的等價條件為起點，分別討論了g - m線性回歸模型、多元線性回歸模型和混合系數線性模型的回歸系數的一類線性有偏估計。
  2. Study the spectral de - aliasing method of image restoration in frequency domain, and offer the improvement with block processing and recursive rstoration to some problems. at the same time, the biased estimate theory is applied in the restoration processing. these improved steps increase the value in the use of data and decrease the time of computation

    2 、研究了基於頻率域的解頻譜混疊方法，針對該方法存在的問題，分別提出了分塊重建和循環重建，提高了重建的效率；並將有偏估計用於重建理論中，提高了影像數據的利用率。
  3. In chapter 3, we discuss the problem of doa estimation in the presence of spatially nonstationary noise fields. an estimate of the colored noise covariance matrix is firstly given. the received data for parameter estimation is then prewhitened using the estimated noise covariance, hence, overcoming the highly biased estimates. finally, adaptive beamforming with the modified weight is also performed. computer simulations show that the proposed method can completely remedy beam distortion. 3

    在第三章討論了一種在環境噪聲為白噪聲而陣元噪聲為空間非平穩情況下的doa估計問題，給出了一種有效的估計陣元噪聲功率的方法，進而利用估計的噪聲協方差矩陣進行預處理而實現色噪聲環境下的doa估計，理論分析和模擬結果均表明了本章提出的方法的有效性。
  4. In chapter 4, we study the outlier mining when the parameter estimate of the given linear model is not least square estimate ( lse ) but uniform biased estimate ( ube ), and present the cook - distance based on the uniform biased estimate, which we use as an important tool in mining influence point

    第四章研究了當線性模型的參數估計不是最小二乘估計而是泛嶺估計時的異常挖掘，給出了針對泛嶺估計的cook距離，用其作為挖掘強影響點的工具。
  5. Study space - time correlation and center biased distribution of motion vector, on which initiate a new fast search algorithm of motion estimate. 4. research the blocking effect of block matching algorithms

    3 、研究了運動矢量的時空相關性和中心偏向特性，提出了一種新的基於運動相關特性和中心偏向特性的快速運動估計演算法； 4 、對塊匹配演算法產生的塊效應進行了研究。
