  • 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。
    Abstract: In order to overcome the problem of ignoring the sensing information between the two fixed thresholds for double-thresholds energy detection algorithm, the sequential cooperative sensing algorithm based on dynamic adaptive double-threshold energy detection is proposed. Since the soft decision between the two dynamic adaptive double thresholds is used for optimizing the probability of detection, it takes sequential cooperative sensing algorithm to model the adaptive double-threshold regions. Furthermore, the proposed algorithm can adaptively adjust the thresholds values and the number of collaborative users for each decision region to optimize the probability of detection and receiver operating characteristics curve. Simulation results show that the proposed algorithm has better performance for the detection capability, compared with other double thresholds sensing algorithms.
