内容記述 | スペクトル拡散 (Spread Spectrum: SS) 通信方式における最も重要な課題の一つは周波数利用効率である.帯域制限のある伝送路にSS方式を適用する場合,データの高速化に伴って処理利得が低下し,SS方式のメリットが生かせなくなる.本論文では,これらの問題に対して有効な新しい並列組合せSS通信方式を提案する.本方式を用いれば,系列長NのN個の直交拡散系列(例えば直交Gold系列)を利用して,送信情報によりN個の系列からr個の系列を並列に組み合わせることにより,(r+log2(NCr)) ビットのデータを同時に送信でき,Nが大きい場合には,例えばr=N/4のとき,Nビットのデータを,またr=2N/3のとき,1.58Nビットのデータを伝送できる.本論文では,並列組合せSS通信方式について,基本原理,システム構成を示し,処理利得と周波数利用効率の関係,組み合わせたr個の系列の誤り率,ビット誤り率,耐振幅制限性,などの特性を解析し,その利点を明らかにする. | |||||
