- 矩阵中的每一个元素称为像元、像素或图像元素。而g(i, j)代表(i, j)点的灰度值,即亮度值。 由于g (i, j)代表该点图像的光强度(亮度),而光是能量的一种形式,故g (i, j)必须大于零,且为有限值,即: 0<=g (i, j)<2n。 用g (i, j)的数值来表示(i, j)位置点上灰度级值的大小,即只反映了黑白灰度的关系。 数字化采样一般是按正方形点阵取样的, -each of the matrix elements known as a pixel, pixe

WidebandAdaptiveAntennaSidelobeCancellationviaExpl
- 本文提出在数字移动通信中子带滤波器组处理可以提高不同阵元信号的相关性,从而能改善自适应阵列抑制码间干扰(ISI)和共信道干扰(CCI)的能力.在文[6]的基础上,本文研究了子带滤波器组在宽带自适应天线旁 瓣相消中的应用,对其原理进行了理论分析,提出了有效的子带处理方法.经研究表明,子带滤波器组处理能有效增加主、辅助天线信号的相关性,从而提高系统干扰相消比.而且适当的过采样能使系统干扰相消比进一步提高.计算机仿真结果和实测雷达数据处理结果证实了子带处理方法的有效性和理论分析的正确性.

PWM
- 采样控制理论中有一个重要结论:冲量相等而形状不同的窄脉冲加在具有惯性的环节上时,其效果基本相同。PWM控制技术就是以该结论为理论基础,对半导体开关器件的导通和关断进行控制,使输出端得到一系列幅值相等而宽度不相等的脉冲,用这些脉冲来代替正弦波或其他所需要的波形。 对不了解PWM的开发人员很有帮助。-Sampling control theory have an important conclusion: the same impulse and different shapes of the
