multi-dimensional signal meaning in English

多维信号

Independent component analysis ( ica ) is a new multi - dimensional signal processing technology developed from blind source separation of late years . some scholars have brought forward a new polarimetric speckle reduction method by using independent component analysis which based on the multi - polarimetric trait of polarimetric sar and the independence between speckle and texture of sar imagery . while the algorithm thinks that there is only one real scene in polarimetric sar source images , so they get only one recovering image in the procedure of image separation and lose polarimetric property
独立分量分析是近年来由盲源分离技术发展来的一种新的多维数字信号处理技术,通过计算数据的高阶统计信息,可以仅从观测信号中估计出互不相关且尽可能相互统计独立的被未知因素混合的原始信号的估计信号,从而帮助实现信号的增强和分析。
