  3. In communication systems, there are mainly two methods for controlling transmission errors, one of which is forward - error - correction ( fec ) and the other is automatic - repeat - request ( arq )

    數據傳輸系統中有兩種技術被用來控制傳輸錯誤：即前向差錯控制技術（ fec ）和自動要求重傳技術（ arq ） 。
  4. This thesis presents a forward error correction ( fec ) algorithm and its circuit implementation, which is used in the wireless digital audio transmission system. also, an entire demo platform is built and error - correction ability of the system is tested based on this platform

    本文研究了一種應用於數字音頻無線傳輸系統中的前向糾錯（ fec ）演算法和相應的電路設計，搭建了一個硬體驗證平臺，並在驗證平臺上完成了電路的誤比特率測試。
  5. This thesis begins with hfc network theory and docsis, analyses modulation / demodulation process of data communication in hfc. then, several theories are analysed including qam ( quadrature amplitude modulation ), nyquist root square filter, fec ( forward error correction ), map ( bandwidth allocation map ). and digital signal transmission involved the other important international standard ? itu - t j. 83 annex a / b, is discussed

    本文從hfc網路理論和docsis協議入手，分析了hfc數據通信的調制解調過程，對qam調制、奈奎斯特均方根濾波器、前向糾錯（ forwarderrorcorrection ，簡稱fec ） 、 map通信等進行了闡述；還從中探討了電纜數據機需要用到的另一個國際標準ituj . 83annexa / b所設計的mpeg信號的數字傳輸。
  6. In this paper, we analyze the statistic characters of time - delay in detail, and put forward to adopt elman nn to forecast time - delay intelligently, design appropriate compensator based on adaptive smith forecast theory. the experiment results prove that this method can improve the forecast accuracy and system ' s dynamic performance. in the application of real time data transmission, forward error correction ( fec ) is a good method to resume the lost data

    針對這個問題本文進行了詳盡的統計特性分析，並且提出採用elman動態神經網路結構對網路時延進行智能預測，並根據自適應smith預估補償控制原理設計合適的時延補償器，並且應用於基於web的二階水位控制系統中，實驗結果證明了採用此方法可以提高預測精度，使時延補償器適應時延變化的動態性更強，從而在保證系統穩定性的基礎上，西安理工大學碩士學位論文提高系統的時延補償精度。
