phase demodulation algorithm 解釋
相位解調演算法
  • phase : n 1 形勢,局面,狀態;階級。2 方面,側面。3 【天文學】(月等的)變相,盈虧;【物、天】相,周相,...
  • demodulation : n. 【無線電】解調,反調制;檢波。
  • algorithm : n. 【數學】演算法;規則系統;演段。
  1. In the second part, the necessity of employing differential demodulation in rapid changing channel was explained, performance of multiple symbol detection of mdpsk and decision feed back multiple symbol detection were analyzed. then we present a new differential demodulation algorithm. the decision data is used to recover the carry phase. given the same observation intervals, this demodulation algorithm has almost the same performance, but the receiver is much more simplified

    第二章首先指出了通道參數變化劇烈的情況下,採用差分解調的必要性;分析了多碼元差分解調和數據判決反饋解調演算法的性能和抑制噪聲的能力;在此基礎上提出了一種新的差分解調方案:利用判決數據輔助進行載波恢復,即在判決數據的輔助下,採用fir ( finantimpounsrespouns )結構對載波相位進行預測的一種演算法,精心設計了該演算法的實現結構。
