  1. Take the hoc based blind modulation detection algorithm as an example, the relationship between the blind modulation detection algorithm and synchronization is investigated. an unproved detection algorithm robust to frequency offset is proposed which solves the problem caused by the error in carrier synchronization. how to synchronize a received signal with unknown modulation type is studied and a blind algorithm to estimate symbol timing of the signals with unknown modulation type is presented

    研究了載波同步和碼元定時同步與調制方盲檢測演算法的關系;以適應單載波中高階累積量調制方盲檢測演算法為例,對于載波同步誤引起的頻偏問題,提出一種基於頻偏穩健的mdpsk信號調制方盲檢測演算法;對于未知調制方信號的定時同步問題,提出一種盲定時估計演算法,該演算法可以估計mdpsk和mqam信號的定時同步信息,實現數字信號的同步分類;提出了一種基於調制方盲檢測的適應結構,把調制方盲檢測,信噪比估計和同步解調聯合起來進行,實現調制方隨通道質量而適應變化的信號的正確
