energy of signals meaning in Chinese
信号的能量
Examples
- The method using wavelet packet analysis is proposed to extract fault information from vibration signal obtained from testing jig of tilting train . the vector comprised of the energy of signal in all spectrum bands is input to a feed forward neural network
利用小波包分析，将摆式车体试验台上采集到的振动加速度信号分解在相互独立的频带之p内，各频带内的能量值形成一个向量，将其作为神经网络的输入特征向量， 。 - Conventional detector ( single - user matched filter ) distinguishes each user by the crosscorrelation of their spread - spectrum codes . in practice , however , its performance is much deteriorated due to the existence of noise in channel and strong multi - access interference , i . e . near for effect . a new method using independent component analysis is proposed in this paper . the - received energy of signals is controlled effectively , thus the near - far effect is overcome as much as possible ; moreover , the effect that noise imposed on the detector is mostly reduced . simulations verify the effectiveness of this method
传统检测器(单用户匹配滤波)利用扩频码之间的互相关特性来区分各用户信号.而在实际应用中，信道噪声和近距离用户对远距离用户的强多址干扰即远近效应，使得接收机的性能受到很大影响.本文将独立分量分析法引入传统接收机，有效控制接收信号的能量，从而极大地提高了接收机的抗远近性能，同时噪声的影响被尽可能消除.仿真结果表明了该方法的有效性和可行性
