Title:
RESTORATION DEVICE, RESTORATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/137641
Kind Code:
A1
Abstract:
A waveform restoration process is reliably performed even in conditions in which the usable calculation amount is limited. This waveform restoration device 10 repeatedly estimates, from a post-clip signal, a pre-clip signal having a prescribed degree of complexity, while increasing the degree of complexity by a prescribed update amount, thereby restoring the pre-clip signal. A parameter determination unit 12 determines a maximum number of repetitions on the basis of the post-clip signal. A waveform restoration unit 13 repeatedly estimates the pre-clip signal using the maximum number of repetitions as the maximum number for the estimate.
