  1. In this paper, the radiolocation technique and principium of ofdm in the cell - communication system were introduced firstly, and sensitivity of ofdm system to synchronization was analyzed. then, two methods of timing synchronization based on the cyclic prefix and pilot sequence were introduced, and a novel timing synchronization method based on pilot sequence was presented, which provided a correlation peak with pulse shape

    由於ofdm系統中的定時同步要求和無線定位中的測時測距在本質上是一致的，所以本文緊接著分析了基於循環前綴和導頻序列的兩種定時同步方法，並提出了一種新的基於導頻序列的具有脈沖形狀相關峰的定時同步方法。
  2. The distributed plc system of the floodgate ' s opening measuring presented by the paper has many advantages such as high reliable operation, high measuring precision, having the network communication function, convenient installation and correction, etc. this thesis further studies the key device for the floodgate ' s opening measuring, the rotary encoder, selects the absolute rotary encoder adopting the binary cyclic code, studies the method for transforming the cyclic code to the binary data and according to the transforming formula designs the ladder diagram program

    本論文研製的分散式plc閘門開度測量系統具有工作可靠、測量精度高、具有聯網通信功能、安裝和校正方便等特點。本論文深入研究了閘門開度檢測的關鍵器件? ?旋轉編碼器，選用了採用二進制循環碼編碼的絕對式旋轉編碼器，研究了將二進制循環碼轉換為二進制數的方法，根據轉換公式設計了plc的梯形圖轉換程序。
  3. Some methods are used to increase the parallel computation efficiency, such as the data cyclic distribution, overlapping of communication and computation, load - balancing in accordance with the computation ability of the dawn - 2000 node, communication mergence and so on
