The time - domain filter can then be used to select the narrow central portion of the cross correlation function ( ccf ) , capturing virtually all of the signal but rejecting most of the noise
對(duì)相關(guān)函數(shù)進(jìn)行時(shí)域?yàn)V波，挑選出互相關(guān)函數(shù)中窄信號(hào)自相關(guān)函數(shù)部分，去掉剩余的大部分噪聲能量，得到加窗互相關(guān)函數(shù)（ ccf ）。
Taking the fourier transform of this windowed ccf produces the time - domain filtered cross spectral density ( tdfcsd ) . the snr can be improved with using the character of noise which distribute uniformly in frequency domain
再進(jìn)行傅立葉變換產(chǎn)生時(shí)域?yàn)V波互相關(guān)譜密度（ tdfcsd ），利用噪聲在頻域中均勻分布的特性使snr得到改善。
