  1. 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

    其中對語音編解碼器的設計採用優化g . 729a代碼達到設計要求，並在此基礎上加入g . 729b的靜音檢測模塊，以進一步降低網路傳輸帶寬;對回聲消除器的設計採用nlms演算法，通過設計自適應fir濾波器和語音檢測器達到回聲消除目的;對雙音多頻設計，信號發生端採用構造靜態參數表並通過二階正弦振蕩器產生信號，信號檢測端提取頻率信息以檢測信號;對呼叫進程音設計，除了類似雙音多頻的信號發生及頻率檢測設計外，還需要檢測信號持續時間，作者設計了一種基於匹配狀態表的方法以檢測信號持續時間。
  2. Comparing with conventional nyquist converters, - converters greatly release the requirements for high performance of analog circuit and precisely matched components. additionally, these converters exploit the enhanced speed, circuit density and low cost of modern vlsi technologies. currentlly, - adcs have been widely used for audio a / d conversion

    - adc採用過采樣噪聲整形技術實現高精度模數轉換，和傳統的nyquist率模數轉換器相比，避免了對模擬電路性能指標和元器件匹配精度的較高要求，並可充分利用現代vlsi的高速、高集成度、低成本的優點，已成為音頻模數轉換的主要技術。
  3. Conventional detector ( single - user matched filter ) distinguishes each user by the crosscorrelation of their spread - spectrum codes. in practice, however, its performance is much deteriorated due to the existence of noise in channel and strong multi - access interference, i. e. near for effect. a new method using independent component analysis is proposed in this paper. the - received energy of signals is controlled effectively, thus the near - far effect is overcome as much as possible ; moreover, the effect that noise imposed on the detector is mostly reduced. simulations verify the effectiveness of this method

    傳統檢測器（單用戶匹配濾波）利用擴頻碼之間的互相關特性來區分各用戶信號.而在實際應用中，通道噪聲和近距離用戶對遠距離用戶的強多址干擾即遠近效應，使得接收機的性能受到很大影響.本文將獨立分量分析法引入傳統接收機，有效控制接收信號的能量，從而極大地提高了接收機的抗遠近性能，同時噪聲的影響被盡可能消除.模擬結果表明了該方法的有效性和可行性
  4. In this paper, the traditional cascode structure of cmos lna is considered as a two - stage amplifier and inter - stage matching network is introduced accordingly

    本文也對cmos低噪聲放大器進行了分析，將傳統共源共柵結構看作二級放大器級聯形式，並由此引入級間匹配網路。
  5. Chapter 3 focuses on translating the c code into assembly code. the implementation and optimization involves issues of assignment of variables and memories, pass of function parameters, addressing modes, control of nested repetition, use of ar registers, pipeline conflicts, and so on

    本文從改寫c源碼為c54x匯編代碼著手，對實現過程中的變量存儲區分配、參數的傳遞、尋址方式的選擇、循環的嵌套與控制、輔助寄存器的使用、流水線等方面的問題進行了設計和優化，在c54x上實時實現了g . 729a聲碼器。
  6. In theoretically, analog optical fiber link can carry out the signal transmission transparently. however, because of the limit of the component level, during the transmission and distribution of the radar signal, noises and interferences from the optic - link may distort the signal and affect the system performance and the array signal processing

    模擬光纖鏈路理論上可以實現信號的透明傳輸，可由於受到器件水平的限制，在整個光傳輸和分配過程中，雷達信號必將受到來自光路噪聲或干擾的污染，從而產生某些畸變和失真，這些非理想因素必然對陣列系統的性能指標和陣列系統的信號處理產生影響。
