Abstract (in Japanese) (See Japanese page) 
(in English) 移動体衛星業務(MSS：Mobile Satellite Services)と地上系移動通信向けシステムの双方に重複して割り当てられた2GHz帯域において，広域に渡る高信頼無線ネットワーク構築のために衛星／地上統合移動通信システム（STICS: Satellite/Terrestrial Integrated Mobile Communication System）等が検討されている．STICSはシステム帯域内に衛星系システムと地上系システムが混在するヘテロジニアス無線ネットワーク構成となっており，互いに使用周波数帯を共有することで周波数の有効利用が図られている．しかしながら衛星系と地上系それぞれに適したチャネル帯域幅が異なり，干渉回避のために衛星系バンドによって分断された不使用地上系バンドが生じる問題があった．本稿では干渉抑圧処理を用いた帯域圧縮伝送を提案し，提案法を地上系のOFDM伝送システムに適用することで，従来の不使用バンドに新たな地上系チャネルを割り当てることで周波数利用効率の改善を図る．計算機シミュレーションにより地上系限界帯域圧縮率を明らかにすると共に，提案法が衛星系に影響を与えないことを示す．また地上系バンドあたりの平均スループットの改善効果について明らかにする。
