Summary:PROBLEM TO BE SOLVED: To provide a fading simulator capable of performing a specified fading, without relying upon the connection method of the operator input.SOLUTION: A fading simulator 20 includes an operation unit 22 for fading the m baseband signals received at m first input ends to which identifiers are attached, respectively, and outputting n baseband signals subjected to fading, and an input control unit 21 for receiving a transmission signal including a pair of the identifier and the baseband signal at m second input end, detecting the identifier included in the transmission signal, and then inputting a baseband signal paired with the identifier, to the first input end to which the same identifier as that included in the transmission signal is attached.SELECTED DRAWING: Figure 1 【課題】本発明の目的は、操作者の入力の接続の仕方に依存せずに指定されたフェージング処理を施すことができるフェージングシミュレータを提供することである。【解決手段】フェージングシミュレータ２０は、識別子をそれぞれに付されたｍ個の第１の入力端で受けたｍ個のベースバンド信号に対してフェージング処理をしてｎ個のフェージング処理されたベースバンド信号を出力する演算部２２と、ｍ個の第２の入力端で前記識別子と前記ベースバンド信号の対を含む送信信号を受けて送信信号に含まれる識別子を検出して、該送信信号に含まれる識別子と同一の識別子が付された第１の入力端へ、その識別子と対のベースバンド信号を入力させる入力制御部２１とを、備える。【選択図】図１
