Abstract

　高速移動受信時の受信性能の低下を効果的に抑制することによって、安定した高速移動受信を可能とするＯＦＤＭ受信装置を提供する。そのために、伝送路伝搬により生じたＯＦＤＭ信号の位相振幅歪みを示す伝送路特性値をサブキャリア毎に算出し、当該伝送路特性値のｎ次微分を算出する伝送路特性推定部と、伝送路特性推定部が算出したサブキャリア毎の伝送路特性値及びｎ次微分を用いて、サブキャリア同士の干渉成分をＯＦＤＭ信号から除去する干渉成分除去部とを備え、伝送路特性推定部は、算出したサブキャリア毎の伝送路特性値をシンボル方向にフィルタ処理することによって１シンボル間隔より短い間隔でオーバーサンプリングし、当該オーバーサンプリングで得られた伝送路特性値のうち２シンボル間隔より短い間隔に存在する伝送路特性値を用いてｎ次微分を算出する。
