Abstract

　複数の物理チャンネルの中からの最適物理チャンネルの決定、及び、最適物理チャンネルに関する合成ダイバーシティ受信のために、合成受信状態と個別受信状態との間で受信状態が遷移する。ここで、合成受信状態から個別受信状態への遷移に際しては、制御ユニット１２０が、乗算係数ＡＴＣを「１」から「０」に連続的に変化させることにより、加算部１７３における選局信号ＩＦＤ1と選局信号ＩＦＤ2と合成比が（１：１）から（１：０）に連続的に変化する。一方、個別受信状態から合成受信状態への遷移に際しては、制御ユニット１２０が、乗算係数ＡＴＣを「０」から「１」に連続的に変化させることにより、加算部１７３における選局信号ＩＦＤ1と選局信号ＩＦＤ2と合成比が（１：０）から（１：１）に連続的に変化する。この結果、再生用に使用するアンテナの増減があったとしても、放送内容の継続的かつ良好な再生を確保することができる。
