  4. And pays emphasis on analyzing the system structure and system flow, the core techniques, the channel characteristic and parameters of dvb - t system. the system adopts some core techniques such as cofdm, a lot of tps ( transmission parameter signalling ) insert and guard interval, and so on. so it can withstand high - level ( up to odb ), long delay static and dynamic multipath distortion

    論文首先描述了數字電視地面廣播的需求條件，技術難點和目前存在的問題，並重點分析了dvb - t系統結構流程，核心技術及系統通道特性和參數，該系統採用了cofdm （編碼正交頻分多路復用） ，大量導頻信號插入和保護間隔技術等核心技術，使之能抵抗高電平（ 0db ） ，長延時的靜態和動態多徑失真，有利於數字和模擬電視的混合傳輸，它的多載波調制模式功能和性能在移動和便攜接收、同頻網等方面具有獨特的優勢。
  5. This dissertation only considers the signal ’ s distortion by interconnect, such as delay, reflection, discontinuity of microstrip, crosstalk and simultaneous switching noise, and so on. nowadays, there are some simulation software in pcb level, but they are lack of the well ability of modeling. in order to simulate the interconnect accurately, we have to make use of three - dimension full wave analysis method, whose disadvantage is low speed in computing, but is competent for developing rules in high - speed designs

    目前也有一些針對這些噪聲的高速pcb板級模擬軟體，但它們都缺乏詳盡的建模能力，特別是當頻率逐漸提高和電路板日益復雜后，更是顯得無能為力，要精確地對互連結構進行分析，三維全波模擬器似乎不可缺少，其缺點就是速度慢，對整板模擬很難實現，但非常適用於規則開發，而這正好是本文除了建模與模擬方法研究外另一個重點。
  6. ( 2 ) a series of experiments on time scale distortion are made with real river model, inflow and outflow boundary condition, and continuous simulation. by means of analysis of the experimental data on model water level, water - surface gradient, cross velocity, outflow discharge process and the sediment transportation capacity, the main physical reasons for the above hydraulic parameters deviations caused by time scale distortion are illustrated : response delay of model channel storage capacity and rate of water level with time

    （ 2 ）採用真實的河工模型和入出流邊界控制條件以及連續模擬的方法進行了有關時間變態率的系列試驗，通過模型水位、比降、流速、出口流量過程線和斷面挾沙力試驗資料的分析，闡明了時間變態引起上述各種水力參數偏離的主要物理原因：模型的槽蓄響應和洪水過程時間變化率的響應滯后。
  7. On the following, on the basis of formulas given above, three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last, the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution

    文中主要研究了電離層的三種影響：信號經過電離層傳播的群延遲引起的成像偏移；電離層的色散效應給線性調頻信號帶來二次相位誤差，導致圖像退化、失真；以及電離層的閃爍、湍流等不規則性引起的信號相位起伏。在此基礎上，比較分析了不同波段、帶寬條件下電離層的影響。
  8. This algorithm adopts peak error or maximum amplitude error criterion to control the level of distortion in pipeline leak signals, and doesn ’ t change the subsequent location error of adaptive time - delay estimation in the case of a small quantization error, so as to implement the near - lossless compression of pipeline leak signals

    該近無損壓縮演算法設計了基於峰值誤差準則的量化方案對管道泄漏信號的失真度進行控制，在量化誤差較小時並不影響后續自適應時延估計的定位誤差，從而實現對管道泄漏信號的近似無損壓縮。
  9. Envelope delay distortion

    波封延遲畸變
