  1. Emphatically, this paper discusses the pattern of signal and antenna radiation of the system, the design principles and technologies of audio - generator and monitor, and the modification of measurement deviation. through special tests and aviate experiments, it has been proved that the performance of the domesticalized system is better than of the initial system

    文中重點分析了俄制分米儀表著陸系統的信號格式和天線輻射場型,著重闡述了系統中信號產生和監測的設計原理和實現技術,對信號測中的測量誤差進行了分析並設計了有效的修正方法。
  2. The master dissertation introduces passive correlative orientation system and base theory in signal dispose briefly in the first place. the system takes tv sound fm signal from tv satation signal. the power rate of tv station signal to sound signal is ten to one. in the case of submerged by mussy weave and machine ' s hot noise, dispersed target signal is feeble

    系統採用電臺的電視伴調信號,其中電臺信號與伴信號功率之比基本為10 : 1 ,並且目標散射信號較弱,一般情況下淹沒在雜和機熱噪聲之下,採用常規的脈沖測方法很難對遠距離的目標進行測,而以電臺直達信號作為參考與目標回信號進行相關測;系統中信號的相關處理會產生旁瓣,而強目標的旁瓣會影響附近的弱目標測。
  3. Section ii describes the design approach and implementation of speech module on mcf5249 coldfire core. the speech codec optimizes g. 729a codes and added voice activity detection of g. 729b to save bandwidth ; the implementation of acoustic echo cancellation uses nlms algorithm and it can reduce echo though designing adaptive fir filter and speech detector ; the dtmf and cpt generate signal using two second order digital sinusoidal oscillators and detect signal by picking up the frequency information. but only get the frequency information is not enough in cpt detector, this thesis introduces a method

    其中對語編解碼的設計採用優化g . 729a代碼達到設計要求,並在此基礎上加入g . 729b的靜測模塊,以進一步降低網路傳輸帶寬;對回聲消除的設計採用nlms演算法,通過設計自適應fir濾和語達到回聲消除目的;對雙設計,信號發生端採用構造靜態參數表並通過二階正弦振蕩產生信號,信號測端提取率信息以測信號;對呼叫進程設計,除了類似雙的信號發生及測設計外,還需要測信號持續時間,作者設計了一種基於匹配狀態表的方法以測信號持續時間。
