差分检测 meaning in Chinese
differential detection
Examples
- However , on the other hand , compared with coherent detection , differential detection comes with an evident loss of performance
但相比于相干检测,差分检测在性能上也会有相当的损失。 - Because of the simplicity of differential detection system , we could consider to apply it to the selective fading channels instead of coherent detection
由于差分检测的简单易实现性,当信道衰落比较严重时,可以考虑采用该方法替代相干检测。 - Another alternative is consists of two steps , the first step is adjacent difference , the second step is to search the motion regions in the frame being processed
在进行运动区域提取时，多数文献都直接采用临帧差分检测法，这种方法会影响检测精度。 - Second is to study the moving object detection by difference between images and the problems produced by thresholding , then enhance the image and get its contour
然后研究了差分检测运动物体后的二值化问题，指出二值化后图像存在的问题以及图像特征增强的方法，并找出运动物体的边缘。 - Because of the time variation of wireless channel , getting the exact channel estimation and good synchronization is difficult for the receiver , so that the differential system could be an attractive choice
由于信道的时变特性,用户的快速移动等原因,在某些无线应用中,对于同步和获得信道的精确估计值都十分困难,在这种情况下,差分检测就成为了一种很有吸引力的方案。
