Abstract

　中継器の経年変化等により伝送路特性が変化した場合であっても、その変化に追従して受信特性の改善を図ることが可能なデジタルデータ送信装置およびデジタルデータ受信装置を提供する。 　送信装置１は、制御情報、データ、外符号パリティ、スタッフビット、内符号パリティからなるＮ本のスロットから成り、同期、パイロット並びに伝送制御信号およびパリティが付加された多重フレームを生成し、各スロットのデータを、伝送制御信号により指定された伝送方式で伝送する。この場合、パイロット信号は、変調方式毎に、予め決められた順に全ての信号点に対して割り当てられたシンボルとする。受信装置２は、パイロット信号により、位相誤差テーブル２１４を書き換えて位相誤差を求め、同期検波を行う。また、尤度テーブル２３５を書き換えて内符号復号を行う。これにより、伝送路特性の歪みに適合した受信処理を行うことができるから、受信特性の改善を図ることができる。
