Description
本発明は、概ね、通信、より具体的には、無線通信システムの直交アップリンクにおけるマルチキャリア符号分割多元接続(multi-carrier code division multiple access, MC-CDMA)を支援する技術に関する。
周波数ホッピング スペクトル拡散(frequency hopping spread spectrum, FHSS)通信システムにおいて、データは、異なる周波数サブバンドまたは副搬送波上で、異なる時間間隔において送信される。この時間間隔は、“ホップ期間(hop periods)”とも呼ばれる。これらの周波数サブバンドは、直交周波数分割多重化(orthogonal frequency division multiplexing, OFDM)、他のマルチキャリア変調技術、または何か他の構成によって与えられ得る。FHSSを使用するとき、データ送信は、サブバンドからサブバンドへ擬似ランダムにホップする。このホッピングは、周波数ダイバーシティを与え、データ送信が、狭帯域干渉、ジャミング、フェージング、等のような有害な経路の影響に、より良く耐えることを可能にする。
