Description:
Originally adopted in military networks as a means of ensuring secure communication when confronted with the threats of jamming and interception, spread-spectrum systems are now the core of commercial applications such as mobile cellular and satellite communication.
This book provides a concise but lucid explanation and derivation of the fundamentals of spread-spectrum communication systems. The level of presentation is suitable for graduate students with a prior graduate-level course in digital communication and for practicing engineers with a solid background in the theory of digital communication. As the title indicates, the author focuses on principles rather than specific current or planned systems. Although the exposition emphasizes theoretical principles, the choice of specific topics is tempered by their practical significance and interest to both researchers and system designers. Throughout the book, learning is facilitated by many new or streamlined derivations of the classical theory. Problems at the end of each chapter are intended to assist readers in consolidating their knowledge and to provide practice in analytical techniques. Principles of Spread-Spectrum Communication Systems is largely self-contained mathematically because of the four appendices, which give detailed derivations of mathematical results used in the main text.

描述:
最初在軍事網絡中被採用作確保在面對干擾和截取威脅時的安全通信手段,展頻系統現在已成為商業應用的核心,如移動蜂窩和衛星通信。本書提供了對展頻通信系統基礎的簡明但清晰的解釋和推導。演示的水平適合具有先前研究生水平數字通信課程的研究生和具有扎實數字通信理論背景的實踐工程師。正如標題所示,作者專注於原則而不是特定的當前或計劃中的系統。儘管講解強調理論原則,但特定主題的選擇受到其實際重要性和對研究人員和系統設計師的興趣的調節。在整本書中,通過許多新的或精簡的經典理論推導來促進學習。每章末尾的問題旨在幫助讀者鞏固知識並提供分析技巧的練習。《展頻通信系統原理》在數學上基本上是自包含的,因為有四個附錄,其中詳細推導了主文本中使用的數學結果。
