  2. First, how to conduct sample and quantification of continuous time signal which is prior condition of sdr is explored in detail, and the comparison and analysis of some sample modes are given in which band pass signal sampling theorem is most important. second, multi - sample rate signal processing which is an important basis of sdr is studied. emphasis are put on decimation and interpolation those are the most fundamental process and the realization of decimation and interpolation filter

    在基於中頻采樣的軟體無線電結構框架下，首先詳細探討了軟體無線電的前提條件，即如何對連續時間信號進行采樣量化，比較分析了幾種采樣的方式，其中最為重要的是帶通信號采樣定理；然後探討了軟體無線電的一個重要基礎，即多采樣率信號處理，重點討論其最基本的兩個過程抽取和內插以及抽取器和內插器的實現；接著介紹了結構簡單、適用於一級抽取的cic濾波器和適用於做2倍抽取的半帶濾波器；再次論文在總結了傳統的調制解調基礎上，結合軟體無線電器件的特點，系統的探討並實現了基於正交思想的am 、 fm 、 ask 、 fsk 、 bpsk 、 qpsk的正交調制解調演算法。
  3. This paper is finished based upon a part of the project, which is the design of delta - sigma adc in a high precision electrical meter chip. i introduce the basic theory of delta - sigma adc in detail and bring forward a way to design 18 bits delta - sigma adc which is successfully used in the project, at the first time the paper introduce the the basic theory of delta - sigma adc and two typical decimation fir digital filters

    本論文主要基於「一種高精度脈沖輸出的電能計量集成電路」項目中關于delta - sigma模數轉換器的設計部分，論文中在對delta - sigma模數轉換器原理進行深入理解的基礎上，提出了一種高精度delta - sigma模數轉換器的解決方案，並運用於以上項目中取得很好的效果。
