Title (EN) RECEPTION TIME ESTIMATION DEVICE
(FR) DISPOSITIF D'ESTIMATION DE TEMPS DE RÉCEPTION
(JA) 受信時刻推定装置
Abstract:
(EN) Provided is a reception time estimation device (20) that estimates the time at which reception of a wave transmitted with a predetermined length of time serving as one transmission opportunity began as an estimated reception time. The reception time estimation device is provided with: a first acquisition unit for acquiring a first time that is a time at which the wave peak value of a received wave exceeded a first threshold value; a second acquisition unit for acquiring a second wave peak value and a second time that is associated with the second wave peak value, said second wave peak value being the wave peak value of the wave at a predetermined timing after the first time and within a period in which the wave peak value of the wave increases and reaches a peak value; and a reception time estimation unit that, on the basis of the first threshold value, the second wave peak value, the first time, and the second time, calculates the time at which the wave peak value of the wave changes from zero as an estimated reception time.
(FR) L'invention concerne un dispositif d'estimation de temps de réception (20) qui estime le temps auquel la réception d'une onde transmise avec une durée prédéfinie servant de possibilité de transmission a commencé en tant que temps de réception estimé. Le dispositif d'estimation de temps de réception est pourvu de : une première unité d'acquisition pour acquérir un premier temps qui est un temps auquel la valeur de pic d'onde d'une onde reçue a dépassé une première valeur seuil ; une seconde unité d'acquisition pour acquérir une seconde valeur de pic d'onde et un second temps qui est associé à la seconde valeur de pic d'onde, ladite seconde valeur de pic d'onde étant la valeur de pic d'onde de l'onde à un moment prédéfini après le premier temps et dans une période dans laquelle la valeur de pic d'onde de l'onde augmente et atteint une valeur de crête ; et une unité d'estimation de temps de réception qui, sur la base de la première valeur seuil, de la seconde valeur de pic d'onde, du premier temps, et du second temps, calcule le temps auquel la valeur de pic d'onde de l'onde change de zéro en tant que temps de réception estimé.
(JA)  所定時間を1回の送信機会として送信される波の受信を開始した時刻を、推定受信時刻として推定する受信時刻推定装置(20)を提供する。受信時刻推定装置は、受信した波の波高値が、第1閾値を超えた時刻である第1時刻を取得する第1取得部と、第1時刻の後であって、かつ、波の波高値が増加してピーク値に達するまでの期間内である所定タイミングで、波の波高値である第2波高値とそれに対応付けられる第2時刻とを取得する第2取得部と、第1閾値と、第2波高値と、第1時刻と、第2時刻とに基づいて、波の波高値がゼロから変化する時刻を推定受信時刻として算出する受信時刻推定部と、を備える。
