有效的估计 meaning in Chinese
the following assessment is valid: number of penetrations feather/down proof
Examples
- We say that ols estimators are asymptotically efficient among a certain class of estimators under the gauss - markov assumptions
我们说在高斯-马尔可夫假定下ols估计量是渐近有效的估计量。 - So in ofdm system , how to synchronize quickly and accurately is quite important , which affects the performance of whole system
因此,在设计ofdm接收机时,需要对符号、频率同步进行有效的估计和补偿,尽可能减小对系统性能的影响。 - In this paper , we have presented a modified music algorithm , which can estimate the doa of coherent signals and adjacent signals with small snr effectively
本文提出的是一种修正过的music算法，该算法能有效的估计出相干信号以及相隔比较近的小信噪比信号的doa 。 - This anfis model combines the neural network adaptive capabilities and the fuzzy qualitative approach such that the soc estimation can be performed in an effective way
自适应模糊推理系统将神经网络的自适应特性和模糊推理结合起来，能够有效的估计电池的荷电状态。 - They are almost based on the theory of conventional detection and estimation . so when the signal to noise ratios of the received signals becomes lower , the performance of these methods take a turn for the worse , and these methods don ’ t work
这些方法大多基于常规信号检测和估计理论,对于宽带微弱的ds信号,当信噪比较低时,这些估计方法的估计性能急剧恶化,不能得到有效的估计结果。
