Description
WS No.197,「〜ディジタル放送/移動通信のための〜OFDM変調技術」,株式会社トリケップス,2000年3月7日
送信される信号であり、緊急信号送信の最大の目的は移動局ユーザが緊急事態にあることを知らせることである。換言すれば、緊急信号により移動局ユーザに緊急事態が生じていることさえ知らせることができればよい。よって、緊急信号は通常信号とは異なり、基地局に受信されさえすれば、その受信品質は劣化していても構わない。
本実施の形態では、ガードキャリアの周波数に緊急信号を配置する。
こで、拡散部107は、配置部106から入力された緊急信号シンボルに対して緊急信号用の拡散コードを用いて拡散処理を行い、拡散後の緊急信号シンボルを無線送信部108に出力する。拡散部107には、移動局100が基地局のセル範囲外に位置する場合でも基地局が緊急信号を確実に受信できる程度のSNR(Signal to Noise Ratio)を得ることができる拡散コードを設定する。
を行い、逆拡散後の緊急信号シンボルを復調部208に出力する。
本実施の形態は、DCキャリアの周波数に緊急信号を配置する点において実施の形態1と相違する。
信する際、DCキャリアf8の周波数のみを対象にして送信処理を行えばよい。このように、本実施の形態に係る配置部106は、マルチキャリア信号の周波数帯f1〜f15において、DCキャリアの周波数に緊急信号を配置する。
ィギュラブル・プロセッサーを利用してもよい。
Claims (3)

配置された前記緊急信号を送信する送信手段と、
を具備する無線通信装置。 - 前記緊急信号を拡散する拡散手段、をさらに具備する、
請求項1記載の無線通信装置。 - 緊急信号の種類、内容または緊急度に応じて、ガードキャリアの周波数またはDCキャリアの周波数に前記緊急信号を配置し、
配置された前記緊急信号を送信する、
緊急信号送信方法。
