  1. In a tdma network, multiple users share the common medium ( or channel ) and bandwidth but different intervals of time. in case of the burst mode, the carrier of the modulated signal needs to be synchronized in a very short time. the common approaches such as a costas - loop and so on are no longer suitable any more

    在一個時分多址（ tdma ）通信網路中，多個用戶通過不同的時間段共享一個傳輸線路（或者通道）的帶寬資源，每個用戶只能在分配給自己的時間段內進行通信，這種突發方式信號的解調要求載波恢復要在很短的時間內完成，我們以往在連續信號解調器中採用的costas環等方法很難適應這種要求。
  2. Based on the communication engineering application, several practical problems been discussed after introducing multi - carrier adaptive multilevel modulation principle. in thesis, alterable channel model been designed and realized dynamic choosing modulated method aggregate to subchannel, and theoretic analysis and computer simulink keep consistent

    本章在詳細介紹多載波自適應多元調制原理的基礎上討論了通信工程中的幾個實際問題，構造了變化的通道模型並基於此實現子通道調制方式集的動態選擇，模擬結論與理論分析一致。
