  1. First, the dissertation researches the characteristics of deep space communication and the popular space communication protocol, such as ccsds, omni etc. according to the functions of communication controller for data link layer protocol, it analyses the characteristics of the channel of space communication both in lunar surface and lunar space, and also provides the relevant controlling projects of data link layer protocol

    首先，研究了深空通信的特點以及應用較為廣泛的空間通信協議，如ccsds 、 omni等空間通信協議族。根據通信控制器對鏈路層協議進行控制的主要功能，分別分析了月地、月上空間通信的通道特點，進而提出了相應鏈路協議的控制方案。
  2. Secondly, we build the physics and mathematical model of space - to - ground optical communication systems. and the link equation is deducted, based on which we calculate the communication link

    其次，建立了空-地激光通信系統的物理和數學模型，得到了空間光通信的鏈路方程，並依據鏈路方程進行了通信鏈路的模擬計算。
  3. Because of the affection of noise and signal fading, in order to high data rate access and high quality, wireless communication need new technology to improve the link reliability and enhance the spectrum efficiency. mimo ( multiple input and multiple output ) can enhance the spectrum efficiency and increase channel capacity greatly, and reduce the multipath affection without spectrum band and power increasing. the 3th generation mobile communication wcdma is coming, with the purpose of putting mimo, stbc ( space time block coding ), space diversity into practice of wcdma systems, in order to lay the foundation of 3g toward 4g, this dissertation has done some research under this background

    在發射機和接收機使用多個天線進行數據傳輸的多輸入多輸出（ mimo ）技術，可以在不增加帶寬和天線發送功率的條件下，成倍的提高頻譜利用率，提高系統的通道容量，還可以抗多徑干擾。第三代移動通信wcdma即將到來，為了將多天線技術（ mimo ） ，空間分集技術，空時編碼技術用到wcdma系統中去，為第三代移動通信向第四代移動通信系統平穩過渡奠定一定的基礎，需要做一些理論上的研究。
  4. One of the core problems in t3d is how to maintain the stability and to promote the transparency of the teleoperation system, on the condition of large time delay and limited bandwidth in the communication link between the operator control station on the earth and the robot workstation in space

    大時延遙操作的一個核心問題是如何在大時延和有限帶寬的條件下，保證遙操作的平穩性，同時提高遙操作的透明性。
