Title:
PRE-EQUALIZED WAVEFORM GENERATION DEVICE, WAVEFORM COMPRESSION DEVICE, AND PRE-EQUALIZED WAVEFORM GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/023869
Kind Code:
A1
Abstract:
A pre-equalized waveform generation device (1000) comprises: a calibration waveform data output unit (1200) that outputs first waveform data for calibration and second waveform data for calibration, the latter being represented by an expression in which the order of a time variable is different from that in an expression representing the first waveform data; a compressed waveform data acquisition unit (1400) that acquires first compressed waveform data indicating a waveform that is modulated using the first waveform data and compressed via a compression transmission line, and second compressed waveform data indicating a waveform that is modulated using the second waveform data and compressed via the compression transmission line; a compression characteristic estimation unit (1500) that estimates a compression characteristic, which is a characteristic of the compression transmission line, using the first compressed waveform data and the second compressed waveform data; and a pre-equalization calculation unit (1800) that calculates pre-equalized waveform data using the compression characteristic and ideal compressed waveform data that is generated on the basis of a signal waveform.
