| INSTRUCTION ON THE SECOND EDITION The first edition of this textbook has been published for 5 years. It is the time to revise it. In addition to error correction and improvement on description, the main differences between the second edition and the first edition are as follows. In recent years, the technology on telemunication works has developed rapidly. Many new working technologies and new work functions emerge endlessly, especially in the field of wireless vehicle munication. Today, cellular vehicle munication work with 4G performance has been spread extensively in China and Wi-Fi has benefited most of the notebook puter and mobile phone users. Bluetooth, RFID, GPS, and NFC are used more and more popular. Those new developed technologies and applications can’t be included in a textbook which is belonging to the scope of fundamental principle of munication. On the other hand, some old working technologies are gradually declined, such as ISDN, ATM, and so forth. Hence, the chapter on munication works in the first edition is deleted. Along with the capacity of munication system increasing and the munication channel rapidly digitizing, multimedia munication has been extensively used. Multimedia technology is closely relevant to source pression coding which includes speech pression coding, image pression coding and digital data pression coding. So, the contents on source pression coding are enhanced in the second edition, and the contents on information theory are reduced. Preface In recent years,munication theory and technology has witnessed rapid development. In China,the application of telemunication service has perated into almost every household and every person. The huge modern munication works have been one of the important infrastructures in China. Correspondingly,the amount of telemunication enterprises and employees there has also been increasing remarkably. Under this situation,the education of the new specialized personnel in the telemunication field and the reeducation of the personnel in service have bee important tasks. In addition,bilingual teaching is a new requirement in Chinese institutions of higher learning,and its importance has been recognized by more and more people. However,there is lack of appropriate textbooks in English on munication theory for Chinese students. This textbook is intended to acmodate the demand. The current munication works in China have almost all been digitized. Signals transmitted in China’s public munication works are mainly digital ones;only the signals transmitted in the user’s loop and those signals for special applications are still analog. Hence,the discussion of analog signal transmission techniques is limited to a minimum,and the greater part of this book is devoted to discussions of digital munication including transforming,encoding and transmission of digital signals,as well as the digitization of analog signals. In the discussion on digital munication technology,some new munication technologies have been emphasized,for example,trellis code modulation (TCM),orthogonal frequency division modulation (OFDM),multiple access,spread spectrum,TURBO code,and so on. Attention has been directed to the explanations that are associated with the application examples of the currently rapidly developed works,such as satellite munication and puter munication works,and so on. In order to best possibly meet the teaching demand in different universities and the demand of the readers who are in active service,this book is divided into two parts. The first part constitutes the basic contents,and is essential for beginners. The second part contains the optional contents,and each chapter in this part is relatively independent. Some chapters in the second part can be selected for learning depending on teaching requirements,some of which can be used as reference for munication engineering personnel. In addition,considering the demands of differen

這本書的排版和插圖處理方式,說實話,有些讓人感到時代的局限性。雖然內容本身或許是經典,但視覺上的呈現卻不盡如人意。很多圖錶看起來分辨率不高,綫條也略顯粗糙,尤其是在涉及噪聲模型和功率譜密度的那些關鍵圖示上,如果能有更清晰的矢量圖來輔助說明,對於理解信號在不同環境下的行為模式會有極大的幫助。我記得有一次在對比不同調製方式的誤碼率麯綫時,因為圖示的模糊性,我不得不花費額外的時間去對照文本描述,反復確認自己的理解是否偏差。此外,書中某些章節的邏輯跳轉略顯突兀,仿佛是從一個非常成熟的知識體係中直接截取瞭片段。例如,從基礎的模擬調製突然跳到數字基帶傳輸時,中間關於采樣定理的詳盡討論似乎被簡化瞭,使得那些依賴綫性係統理論的讀者可能會感到過渡不夠平滑。當然,如果把這本書定位為研究生階段的參考資料,或許這些都可以被接受,但對於希望通過自學建立完整知識框架的讀者來說,這種閱讀體驗算不上是完全順暢的。
評分從語言風格上來說,這本書的英文錶達是極其精確和嚴謹的,完全符閤頂級學術著作的標準。每一個術語的使用都恰到好處,沒有絲毫的模糊地帶,這對於希望提高專業英語閱讀水平的非母語讀者來說,是一個極好的學習資源。作者的寫作風格是那種典型的、不帶任何感情色彩的陳述方式,直指核心,力求在最短的篇幅內傳遞最豐富的信息量。然而,正是這種極緻的精煉,使得文本的“可讀性”在某些時刻被犧牲瞭。在介紹如均衡器設計這類需要空間想象力的內容時,如果能輔以更多形象化的比喻或者更生活化的語境來軟化一下硬邦邦的數學描述,我想即便是像我這樣在閱讀學術文獻方麵略顯疲憊的讀者,也能從中獲得更多的樂趣和更持久的閱讀動力。總而言之,這是一本需要投入大量精力和專注力去啃讀的硬核專業書籍,它提供的知識深度是無可置疑的,但閱讀體驗的友好度則需要讀者自行去平衡。
評分這本書的習題部分是我個人認為最值得稱道,同時也最讓我感到挫敗感的地方。每一章末尾的練習題設計得非常巧妙,它們並非簡單的公式套用,而是常常要求讀者對所學概念進行靈活的組閤和深入的思考。有的題目甚至需要結閤高等數學和概率論的知識進行綜閤運用,這無疑是檢驗學習效果的絕佳方式。然而,這種難度也意味著,沒有詳細的解答或清晰的解題思路引導,對於自學者來說,卡住一個問題就可能導緻整個章節的學習停滯不前。我發現,書中幾乎沒有提供任何例題的逐步解析,這使得那些在解題過程中遇到睏難的讀者,缺乏及時的反饋和指導。這本教材的定位似乎是麵嚮那些有導師指導或者已經有堅實基礎的研究人員,它鼓勵的是獨立發現問題的能力,而非手把手的教學。對於那些希望通過大量練習來鞏固知識點的學習者來說,缺少配套的答案解析是一個不小的遺憾,極大地影響瞭學習的效率。
評分這本書的封麵設計很吸引人,那種簡潔而專業的風格立刻讓我對接下來的閱讀充滿瞭期待。然而,當我真正翻開書頁,深入到那些復雜的公式和理論時,我纔意識到這不僅僅是一本教科書,更像是一場智力上的馬拉鬆。作者似乎非常鍾愛那些深奧的數學推導,每一個概念的引入都伴隨著大量嚴謹的證明過程。對於初學者來說,這無疑是一個巨大的挑戰。我花瞭大量時間在理解傅裏葉變換、捲積等基礎概念上,感覺自己仿佛迴到瞭大學時代,需要一遍遍地翻閱參考資料來鞏固那些看似抽象的知識點。特彆是關於信道編碼的部分,那些關於糾錯能力的討論,雖然在理論上令人嘆為觀止,但在實際應用層麵的直觀感受卻有所欠缺,讓人不禁想知道,如果能增加一些更貼近現代通信係統的實例分析,效果會不會更好一些。整體而言,這本書的深度毋庸置疑,它為那些渴望建立紮實理論基礎的讀者提供瞭豐富的養料,但其高強度的學術密度,確實需要讀者有相當的耐心和毅力纔能消化。
評分我購買這本書的初衷是想全麵梳理一下信息論與通信係統設計之間的內在聯係,特彆是希望能在容量限製和實際傳輸速率之間找到一個清晰的平衡點。坦白地說,這本書在信息論部分的處理可謂是深入骨髓,香農的每一個定理都被拆解得非常透徹,那種對信息本質的追問,讓人讀後對“信息”二字有瞭全新的敬畏感。然而,當我們將目光轉嚮更偏嚮工程實踐的章節時,比如多址接入技術和擴頻通信,這種理論的“高冷”感便體現齣來瞭。書中對這些技術的描述,更多停留在數學模型構建和性能分析的層麵,對於如何在實際的硬件約束下進行權衡和優化,提及得相對較少。比如,在討論MIMO係統時,雖然提到瞭奇異值分解的重要性,但對於實際信道狀態信息(CSI)的獲取和反饋機製在復雜無綫環境下的挑戰,並沒有給予足夠的篇幅去探討。因此,這本書更像是一座理論的高塔,它嚮我們展示瞭通信係統的“天花闆”在哪裏,但通往這座高塔的實際路徑圖,讀者需要自己去繪製。
