Unusable channel / Channel subject to interference Explanation: It's defined in the claimed scope section of the patent. It talks about a dedicated channel used to communicate the IDs of channels that are subject to interference Quoted from http://www.j-tokkyo.com/2001/H04J/JP2001-148682.shtml : 特許請求の範囲 請求項1 供給される情報信号を、OFDM方式により変調して送信するマルチキャリア送信装置において、この装置より送出された信号を受信するマルチキャリア受信装置より送信される、OFDM信号を構成するそれぞれのキャリアのうち受信品質が不良であると指定されるキャリア番号情報を受信する不調キャリア受信回路と、前記供給される情報信号と、その情報信号に付加される誤り訂正信号を、前記不調キャリア番号のキャリアを除くマルチキャリアを用いて伝送するOFDM信号を生成するためのOFDMフレーム構成回路と、そのOFDMフレーム構成回路より供給された信号を基にOFDM信号を生成するIFFT回路と、IFFT回路により生成された信号を送信信号に変換して送信アンテナに供給する高周波回路と、より構成されることを特徴とするマルチキャリア送信装置。 |
