  1. It ' s an e. l. t. - - emergency location transmitter

    這是一個elt . . .求救信號發射器
  2. It ' s an e. l. t. - emergency location transmitter

  3. In the spread spectrum communication system, the synchronization of receiver ' s persedo - noise ( pn ) code to the transmitter ' s pn code is such an important part that the whole system ca n ' t work at all without it

    在整個擴頻系統中，接收端對發端擴頻碼的捕獲和同步，是一項決定整個系統成敗的至關重要的技術。
  4. It can be used in any complex environment, can locate all paths from transmitter to receiver which avoid redundant calculation, and it is a standard 3 - d forecast model ; in addition, it is a point to point ray tracing method based on specular theory which do n ' t carry out the receive test ; furthermore the model adopt the reverse arithmetic which exert the tree concept in data frame and establish a virtual fountain tree permanently, the proagmme can back - search the virtual fountain tree when it is running. these operation increase the calculate speed and it result in the higher receive efficiency and precision. the thesis design a programme to compare the prediction results based on ray tracing method of virtual fountain tree between the measurement results and prediction results based on the other transmittion models. the comparsion result indicate the new model is a better model

    它可應用於任何復雜的傳播環境中，能找到發射機到接收機之間的所有電波傳播路徑而無須冗餘的計算，是一種準三維的預測模型；另外，從本質上講，它仍然是一種基於鏡像理論的點對點的射線跟蹤法，所以它無須進行接收測試；而且由於採用了反向演算法，運用數據結構中多叉樹的概念，先確定需要計算的場點位置，找出所有能從源點到達場點的射線，並且可一次性建立一個虛擬源樹，以後每次的計算只要通過對該樹進行後序遍歷即可，大大提高了運算速度，因而有較高的接收效率與精度。本文對該模型進行了相應的模擬，並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射線跟蹤確定性模型的預測結果進行了比較，結果表明了該模型的優越性。
  5. The assumption that the channel is known is questionable in a rapidly changing mobile environment, or when multiple transmitter antennas are employed. unitary space - time codes and differential unitary space - time codes do n ' t need any channel information. we discuss the unitary space - time codes briefly and study the details of the dustc, including the fundamental differential transmission and receiver equation, and parameters searching algorithm. the parameters searching and simulations results is proposed

    酉空時編碼及酉差分空時編碼（ dustc ）都不需要通道信息，著重研究了酉差分空時編碼技術，簡要說明了酉空時編碼的信號形式及星座設計方法;分析了dustc的發送和接收公式，分析了dustc的嚴格pep和sep的聯合界，給出了當snr值在不同的范圍時， dustc星座參數的選取準則，並進行了rayleigh衰落通道的模擬。
  6. Kn, kg, t, m or litres. the piston of this force transmitter is designed to adapt itself to the face of the piston acting on it up to an angle of approx

    這個力傳送器的活塞設計上可以使它在大約正負3內適應與他作用的活塞表面。
