查询词典 estimating

This paper introduces a novel technique for estimating the signal power spectral density to be used in the transfer function of a microphone array post-filter.The technique is a modification of overestimation of noise power spectral density of the existing Zelinski post-filter and McCowan post-filter,which utilize the auto- and cross- spectral densities of the signals.Near-field compensation is taken into account.

介绍了一种用于近场麦克风阵列后滤波语音增强的方法，避免了现有的利用自功率谱密度和互功率谱密度的Zelinski和McCowan后滤波器中噪声功率谱过估计的问题，并加入了近场传播的幅度衰减补偿和相位延迟补偿。

Interpath interference which arises due to non-zero cross and auto correlation of more than one spreading code is suppressed by estimating a transmitted signal stream, or a plurality of such signal streams in the case of a plurality of multipath components, respreading this estimated signal and subtracting non-orthogonal interference contributions from a received signal.

The octane number of 5 substances were predicted using the new methods.The results show that the second level group contribution method exhibits significant improvements in accuracy and should be used for estimating the octane number of branched and ring hydrocarbons.In cases of simple straight chain bydrocarbons, however,the first level group contribution method should be used.

用新方法对未参加回归的五种物质的辛烷值进行了预测，结果表明对于含有支链和环的烃应采用第二水平基团法估算其辛烷值，对简单的直链烃采用第一水平基团法估算其辛烷值。
