- 噪声功率比(NPR)这个概念自频分多路复用(FDM)电话系统诞生之初即已出现。简单而 言,NPR用于衡量多通道系统中当其他通道上存在随机活动时,某个闲置通道的“安静”程 度。噪声和交调失真产物进入该闲置通道,从而降低性能。该概念最初用来检查FDM链 路中的4 kHz宽语音通道,如今,在确定多通道宽带通信系统的特性时也是有用的——但在 现代测量技术方面,存在一些重要的区别。-The concept of the noise power ratio (NPR) from the fr

- We propose a protocol for secure mining of association rules in horizontally distributed s. The current leading protocol is that of Kantarcioglu and Clifton [18]. Our protocol, like theirs, is based on the Fast Distributed Mining (FDM) algorithm of
