本書是美國麻省理工學院(MIT)知名教授奧本海姆的近年力作,是其在MIT開展了二十余年的Signals, Systems and Inference課程所涉及知識體系的拓展和延伸。本書詳細闡述了確定性信號與系統(tǒng)的性質(zhì)和表示形式,包括群延遲和狀態(tài)空間模型的結(jié)構(gòu)與行為;引入了相關(guān)函數(shù)和功率譜密度來描述和處理隨機信號。本書涉及的應用實例包括脈沖幅度調(diào)制,基于觀測器的反饋控制,最小均方誤差估計下的最佳線性濾波器,以及匹配濾波器;強調(diào)了基于模型的推理方法,特別是針對狀態(tài)估計、信號估計和信號檢測的應用。本書融合并擴展了信號與系統(tǒng)時頻域分析的基本素材和概率論知識,這些都是信號處理、控制、通信、金融工程、生物醫(yī)學工程等工程和應用科學領(lǐng)域的基本分析方法。
