Title (EN) RECEPTION SIGNAL PROCESSING DEVICE
(FR) DISPOSITIF DE TRAITEMENT DE SIGNAL DE RÉCEPTION
(JA) 受信信号処理装置
Abstract:
(EN) A reception signal processing device is provided with: a conversion unit which coverts an analog signal amplified by an amplification unit to a digital signal; a switch provided at the latter step of each variable gain amplifier of the amplification unit; a detour switch unit which sets opening/closing of a path through which the output of a variable gain amplifier bypasses the variable gain amplifier in the latter step, and is input into the conversion unit; a switch control unit which controls the switch and the detour switch unit; and a DC offset control unit which sets a correction value for a DC offset in accordance with the gain set in the gain-variable amplifier to be corrected.
(FR) L'invention concerne un dispositif de traitement de signal de réception comprenant : une unité de conversion qui convertit un signal analogique amplifié par une unité d'amplification en un signal numérique ; un commutateur présent au dernier étage de chaque amplificateur à gain variable de l'unité d'amplification ; une unité de commutation de dérivation qui définit l'ouverture / la fermeture d'un chemin à travers lequel la sortie d'un amplificateur à gain variable contourne l'amplificateur à gain variable dans le dernier étage et est appliquée à l'entrée de l'unité de conversion ; une unité de commande de commutateur qui commande le commutateur et l'unité de commutation de dérivation ; et une unité de commande de décalage CC qui définit une valeur de correction pour un décalage en CC en fonction du gain réglé dans l'amplificateur à gain variable à corriger.
(JA)  受信信号処理装置は、増幅部により増幅されたアナログ信号をデジタル信号に変換する変換部と、増幅部の各利得可変増幅器の後段に設けられたスイッチと、利得可変増幅器の出力が後段の利得可変増幅器を迂回して変換部に入力される経路の開閉を設定する迂回スイッチ部と、スイッチ及び迂回スイッチ部を制御するスイッチ制御部と、補正対象の利得可変増幅器に設定される利得に応じてDCオフセットの補正値を設定するDCオフセット制御部とを含む。
