  • 摘要: 在大型建筑底層及偏遠(yuǎn)地區(qū)等,傳統(tǒng)的蜂窩網(wǎng)系統(tǒng)沒(méi)有提供可靠的無(wú)線覆蓋。該文采用中繼方式延伸基站的無(wú)線覆蓋至目標(biāo)區(qū)域。主要研究最優(yōu)的中繼部署與功率分配最小化目標(biāo)區(qū)域的最大中斷概率。功率分配是指在總功率受限的情況下,最優(yōu)化基站和中繼的發(fā)送功率。通過(guò)分析可以得到最優(yōu)的中繼部署,基站和中繼發(fā)送功率的比值不隨總功率的增加而變化。針對(duì)優(yōu)化問(wèn)題的非凸性質(zhì),提出了一種獲得局部最優(yōu)解的算法。通過(guò)仿真可得給出算法的性能與窮搜索算法的性能基本重合。由于給出算法的復(fù)雜度較低,更適用于實(shí)際的系統(tǒng)。
