Optimal time-delay spiking deconvolution and its application in the physical model measurement

Zhengsheng Yao, Gary F. Margrave and Eric V. Gallant

ABSTRACT

Spike deconvolution based on Wiener filter theory usually has the desired output as a zero-lag spike, which works well for wavelets of minimum phase. In this paper, the algorithm that extends the standard spiking deconvolution to mixed-phase wavelet is presented. The optimal output spike has a time delay, determined from the projection matrix, and forms an optimal time-delay spiking deconvolution. The application of this algorithm to physical model measurements shows that this technique is efficient for the case when the wavelet is well determined.
