  分数时延估计文档对于宽带信号, 基于移相的窄带波束形成方法会导致方向图波束指向的偏移和主波束畸变, 并且无法有效地抑制宽带干扰。该文提出了基于数字时延加抽头延迟线 (tapped delay line , TDL)结构的宽带自适应波束形成方法。 该方法采用数字时延滤波单元补偿宽带信号在波束指向上的相位和包络偏移, 并用基于TDL 的空时二维滤波处理抑制宽带干扰。分析和实验结果表明, 该方法可以有效地合成空间宽带波束并抑制宽带干扰, 提高信干噪比(sig nal-to-interference-plus-noise r atio , SINR)增益。(frac delay estimation)

    去噪处理是图像处理中较为重要的环节。中值滤波是抑制图像的噪声的一个行之有效的办法,选择适当大小的中值滤波窗口可以在最大限度的保持图像精度的基础上去除图像噪声。本文在对中值滤波去噪算法的适用性特点进行研究的基础上,进一步研究了中值滤波去噪算法,同时对其他去噪算法,如均值滤波、低通滤波的小波变换进行分析研究,并做了相应的比较。(Noise reduction is one of the most important parts of image processing. Median filtering is a proven way to remove image noise. To select the appropriate size of the window can maximize to remove image noise on the basis of maintaining the accuracy of the image. On the basis of investigating the application of the median filtering algorithm denoising characteristics, we do further study of the median filtering algorithm denoising. At the mean time we analyzed the mean filtering and wavelet transform algorithm, and compared them.)
