  4. This thesis adopts 8psk / qpsk modulation mode that ' s widely applied in short - wave communication to research all - digital blind receiver in burst mode based on software radio technology. then related solutions are given for the doppler frequency shift problem and multiple fading problem in short - wave channels. the arrangement of the thesis is below : chapter 1 gives brief description for the new technology and new systems of short - wave communication and for the development and appliance of software radio

    本文採用短波通信中應用廣泛的8psk qpsk調制方式,研究基於軟體無線電技術的突發模式全數字盲接收,並對多音并行及慢速傳輸中存在的多譜勒大問題、單音串列、高速數傳時在短波通信鏈路中發生的干涉衰落問題做了研究,提出了相應的解決方案。
  5. 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式盲檢測演算法的關系;以自適應單載波中高階累積量調制方式盲檢測演算法為例,對于載波同步誤差引起的問題,提出一種基於穩健的mdpsk信號調制方式盲檢測演算法;對于未知調制方式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式盲檢測的自適應接收結構,把調制方式盲檢測,信噪比估計和同步解調聯合起來進行,實現調制方式隨通道質量而自適應變化的信號的正確接收。
