    考慮到目標信息提取的相對完整性，以高頻雷達為背景，在對多載波相位編碼脈沖串信號參數設計的基礎上，推導了三種多載頻相位編碼脈沖串信號的距離速度二維處理過程並相應的對多目標噪聲環境進行了模擬;將多載波相位編碼信號與另外兩種距離高分辨信號:單載頻相位編碼信號和相位編碼階梯跳頻信號，在信號特性、處理過程和抗噪聲特性方面進行了對比;本文從理論上為多載波相位編碼信號的波形設計和分析、信號的處理打下基礎。
  4. In this thesis, a qpsk channel monitoring solution is applied. by monitoring the parameters of carrier power, c / n rate and noise of the channels, analyzing their changes, and judging by these parameters, alarms of interferences of illegal signals are implemented

    本課題中採用qpsk通道監測方案，通過監測通道中的信號狀態參數:載波功率（ power ） 、載噪比（ c / n ）和噪聲（ noise ） ，分析它們的變化情況，並進行綜合判決，最終實現對非法信號干擾的報警提示。
  5. We made an improvement in overcoming the defects in speech signal adaptive delta modulation ( abbr. adm ), such as slope overloading and grain noise. in this method, numerical sliding average filtering was used for filtering decoding speech signal. experiments and analyses indicate that the method makes waveforms in good agreement between the decoding of adm and the original pulse coding modulation ( abbr. pcm ) signal, and considerably improves, the playback speech quality in naturalness, legibility and under standability

    針對語音信號自適應增量調制（ adm ）方式中斜率過載和顆粒噪聲缺點，提出了一種改進方法，它利用滑動平均方法對解碼后的信號進行數字濾波.試驗和分析表明，該方法使解碼后的信號波形與原脈沖編碼調制（ pcm ）波形具有很好的一致性，使再生語音質量在自然度、清晰度和可懂度方面比改進前均有較大提高
