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。 -

本論文首先對吉林化纖長絲車間生產管理進行系統現狀分析，其主要目的是查找生產管理系統存在的問題，並進行系統原因分析，從而確定系統優化方向。文章從生產計劃管理、生產組織管理、生產控制管理三個方面作了系統現狀分析，逐一闡述車間生產管理各個子系統存在問題有原因分析，在此基礎上運用生產管理系統優化理論，對車間生產管理各個子系統進行了優化研究，提出了系統優化方案。為保證車間生產管理系統優化方案能夠順利實施，筆者提出通過車間自身生產管理制度建設、績效考評系統建立、員工培訓體系建立、生產現場5s管理推行及車間班組建設，為車間生產管理系統優化提供更有力的保障。
