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.
