  • 摘要: 針對(duì)在一般高斯白噪聲環(huán)境中,傳統(tǒng)的雙門限能量檢測(cè)頻譜感知算法忽略確定兩門限之間的感知信息的問題,該文提出一種基于動(dòng)態(tài)自適應(yīng)雙門限能量檢測(cè)的序貫協(xié)作頻譜感知算法。新算法以最優(yōu)化檢測(cè)概率為目標(biāo),采用序貫方式對(duì)協(xié)作用戶進(jìn)行動(dòng)態(tài)自適應(yīng)雙門限建模,并對(duì)處于兩門限之間的接收能量值進(jìn)行軟判決。進(jìn)一步地,新算法能自適應(yīng)動(dòng)態(tài)調(diào)整門限大小和各判決區(qū)域協(xié)作用戶數(shù),以達(dá)到最大化檢測(cè)概率和最優(yōu)化受試工作特征曲線的目的。理論分析和仿真結(jié)果表明,與經(jīng)典的雙門限能量檢測(cè)算法相比,提出算法具有更優(yōu)的檢測(cè)概率。
