چکیده
あらまし 次世代移動通信システムの実現に向けてバーチャルセルラネットワーク(VCN)が提案されている.送信電力の制 限された環境下において伝送速度が高速化した場合,従来のセルラネットワーク(CN)では通信可能なエリアが狭まり,セル端付 近の移動局は通信できず,呼損となってしまう.VCN ではマルチホップ通信の適用により送信電力を増大させることなく,通 信エリアを拡大できる.そのため,送信電力が制限された環境下において従来のシングルホップ CN に比べ,呼損率を改善する ことが可能である.本論文では,2ホップ VCN について計算機シミュレーションにより呼損率を求め,その導入効果を明らか にしている.また,VCN に maxSINR チャネル割当て法を適用したときの呼損率を求め,チャネル棲み分け法と比較している. キーワード バーチャルセルラネットワーク,2ホップ,チャネル棲み分け,maxSINR,呼損

Blocking Probability of a DS-CDMA Multi-Hop Virtual Cellular Network
A wireless multi-hop virtual cellular network (VCN) was recently proposed to avoid the large peak transmit power, resulting from the high transmission rates expected for future mobile communication systems. In VCN, calls hop through several links to reach the central port, which is the gateway to the network. With the use of a routing algorithm based on the total uplink transmit power minimizat...
