內(nèi)容概要

本書系統(tǒng)地總結(jié)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(gòu)及其應(yīng)用的研究成果,覆蓋了關(guān)于混純信號重構(gòu)的基本問題和幾個(gè)高層次的問題。共分為四個(gè)層次進(jìn)行深入的論述:1在無噪聲的信道里如何重構(gòu)原始混沌信號,這是將Takens定理推廣到時(shí)變的連續(xù)時(shí)間與離散時(shí)間系統(tǒng),2如何通過噪聲污染的混沌信號重構(gòu)原始混沌系統(tǒng)的動(dòng)力學(xué),3如何通過噪聲污染同時(shí)也被信道畸變的混沌信號重構(gòu)原始混沌系統(tǒng)的動(dòng)力學(xué),4基于混沌同步的思想重構(gòu)原始混沌系統(tǒng)的動(dòng)力學(xué)。所有這些問題都是圍繞基于混沌的寬帶通信在實(shí)際通信環(huán)境里的實(shí)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(dòng)化等學(xué)科的大專院校高年級學(xué)生和有關(guān)研究人員具有很強(qiáng)的可讀性和重要的參考價(jià)值,并能起到拋起引玉的作用。
