  • 摘要: 針對解調數(shù)據(jù)有無物理幀結構的檢測問題,該文提出了一種基于多重分形譜的物理層幀結構檢測算法。首先,在定義序列有偏性與0, 1出現(xiàn)概率關系的基礎上,根據(jù)編碼序列、擾碼序列和物理幀的生成原理,通過計算相關序列中的0, 1出現(xiàn)概率推導出它們的有偏性關系,即物理幀、編碼序列和擾碼序列的有偏性逐漸減小;然后,利用上述結論并結合多重分形譜具有描述有偏性分布的特點,對待識別序列進行固定長度拆分并計算多重分形譜寬度值;最后,通過觀察多重分形譜寬度值的分布實現(xiàn)解調數(shù)據(jù)有無物理幀結構的檢測。仿真試驗驗證了算法的有效性,表明該算法具有一定的工程應用價值。
