內容概要
本書系統(tǒng)地總結了作者近年來涉及的嵌入在基于混沌的通信中的最基本問題——混沌信號的重構及其應用的研究成果,覆蓋了關于混純信號重構的基本問題和幾個高層次的問題。共分為四個層次進行深入的論述:1在無噪聲的信道里如何重構原始混沌信號,這是將Takens定理推廣到時變的連續(xù)時間與離散時間系統(tǒng),2如何通過噪聲污染的混沌信號重構原始混沌系統(tǒng)的動力學,3如何通過噪聲污染同時也被信道畸變的混沌信號重構原始混沌系統(tǒng)的動力學,4基于混沌同步的思想重構原始混沌系統(tǒng)的動力學。所有這些問題都是圍繞基于混沌的寬帶通信在實際通信環(huán)境里的實現(xiàn)為研究目的。 該書對于信號與信息處理、非線性電路、通信、智能信息處理和自動化等學科的大專院校高年級學生和有關研究人員具有很強的可讀性和重要的參考價值,并能起到拋起引玉的作用。
