中文摘要 | 近年來,非線性系統理論廣泛之討論研究,其中,尤以混沌理論最被注意,對於其複雜且有趣的現象,令人印象深刻。國內外學者及期刊中多有研究及文獻發表;目前,大家的眼光集中在其應用之領域。本文即是將混沌信號應用於展頻通訊上。一般混沌信號具有幾項優點:(1)信號具展頻特性(2)且有良好的自相關互(3)產生混沌信號源簡單。以上的特性,很適合於特定之通訊應用,可做為有別於傳統通訊系統之選擇參考。本文是研究CDMA展頻通訊系統中,PN碼由混沌信號來產生,並討論此PN碼之特性。最後,將以計算機模擬來驗證混沌信號可應用於展頻通訊系統中。 |
英文摘要 | In the last few years there has been much interest in the studies of chaotic and complicated phenomena in systems. Numerous journals have been devoted to the analysis of such phenomena in systems. This paper focuses on applications of the theory of chaotic circuit to communication systems. There are some advantages found in chaotic communication systems: (a)transmitted signals have spread spectrum (b)good auto-correlation and cross-correlation properties (c)generation of chaotic signal is simple. The major aim of this project is to investigate applications of chaotic signals to generate a PN sequence of spread-spectrum communication system. Finally, computer simulations will be provided to illustrate our analysis. |
