In the scheme, a set of feature parameters are extracted from signal spectrum and constellation based on the differences between digital mixed signals and common digital modulation signals.
该方案利用数字混合信号与常用数字调制信号在信号频谱以及星座点的差异提取特征参数进行自动识别。
Besides common geometric measurements such as distances and angles, a new measurement of average curvature energy defined for boundary curve segment is included in the set to describe curve feature.
除了常见的几何测量(如距离和角度)外，提出了一种平均曲率能量的测量方法来描述边界曲线特征。
Second, standards support and encourage interoperability amongst multiple vendors by defining an agreed upon minimum base feature sets and a set of common test points at interfaces.
第二，通过定义一个被认可了的最小基础特性集和一系列通用测试接口点，标准支持和鼓励多厂家的互操作。
