Title:
MULTIPATH ANALYSIS DEVICE AND PROGRAM
Document Type and Number:
Japanese Patent JP2023003736
Kind Code:
A
Abstract:
To flexibly set a sampling frequency or a sampling period and to also analyze a multipath of a short delay time.SOLUTION: A multipath analysis device comprises an amplitude frequency characteristic acquisition unit, a delay time acquisition unit, a parameter acquisition unit, a calculation unit, an error detection unit, an extraction unit and an output unit. The amplitude frequency characteristic acquisition unit acquires a first amplitude frequency characteristic. The delay time acquisition unit acquires a first delay time which is a candidate of a delay time of a reflection wave included in a radio wave. The parameter acquisition unit acquires a predetermined parameter. The calculation unit calculates a second amplitude frequency characteristic which is a predicted amplitude frequency characteristic based on the first delay time and the parameter. The error detection unit detects an error of the first amplitude frequency characteristic and the second amplitude frequency characteristic. The extraction unit extracts a second delay time which is the delay time of the reflection wave included in the radio wave based on the detected error. The output unit outputs the extracted second delay time.SELECTED DRAWING: Figure 1
