为解决现有抽取算法要求全局唯一定位器，以及不能识别含有可选无序或噪声成分的对象等问题，本文提出了一种称为l -树匹配的通用抽取算法。 - This method uses two spatially separated receiving equipment . cross correlation of the two outputs will therefore yield the auto correlation function ( acf ) of the signal , plus noise which is spread uniformly over the whole width
该算法采用空间上分离的两路接收设备，通过对包含同一个信号的2个输出信号互相关，得到信号窄自相关函数（ acf ）和在整个带宽里均匀分布噪声成分。 - In the wi coder , the speech signal is represented by an evolving characteristic waveform ( cw ) . the cw is decomposed into a slowly evolving waveform ( sew ) and a rapidly evolving waveform ( rew ) , representing the quasi - periodic and non - periodic components of speech , respectively
Wi编码器将语音信号表示为渐变的特征波形( cw ? characteristicwaveform ) ，然后将其分解为慢渐变波形( sew ? slowlyevolvingwaveform )和快渐变波形( rew ? rapidlyevolvingwaveform ) ，分别表示语音的准周期成分和类噪声成分。 - The exhaust noise contains complex noise elements , including the exhaust noise with a base frequency measured in the number of exhausts in unit time , the resonance noise of the gas column in the pipe , the gas stream blowing noise at the exhaust manifold , the exhaust gas jetting and impact noise , the helmholtz resonance noise of the cylinder , the karman eddy noise and the turbulent noise inside the exhaust system
排气噪声包含了复杂的噪声成分：以单位时间内排气次数为基频的排气噪声、管道内气柱共振噪声、排气歧管处的气流吹气噪声、废气喷注和冲击噪声、汽缸的亥姆霍兹共振噪声、卡门涡流噪声及排气系统内部的湍流噪声等。
