This course focuses on the analog communications. . However, we will still include a very brief introduction digital communications; while a sequential course (the principles of digital communications) mainly covers the more advanced topics in digital communications. After a brief introduction to the general communication systems (1), we review the important concepts on the description and analysis of signals and systems (2-3). The basic analog modulation methods and receiver designs are introduced in (4-6). The emphasis is placed on the treatment of the analog communications as the necessary background for understanding the digital communications. Examples are provided to illustrate the extensions of analog transmission to digital transmission and the differences between the digital and the analog systems. The evolution from analog systems to digital systems is developed gradually by introducing various pulse modulation techniques (7-8). In (9-10), the baseband digital communication system is described. Then, the discussions of noise in a rigorous way become the next major topic. The necessary mathematical tools, probability and random processes, are then studied in (11-14). (Actually, the signals, in addition to the noises, are modeled by random processes.) These tools are employed to study the noise effect on the performance of analog signal transmission (15-16), and they are also essential in understanding the many issues in the digital communications (17). In the last lecture, more will be said on the comparison and differences between the analog and the digital transmission systems. Computer simulations help learners in understanding the operations of communication systems. It is important for the students to master a few programming tools (Matlab or C language) in this course. Computer simulations will be counted as a sizable portion in the homework assignments. 本課程為瞭解通訊系統的入門課,之後銜接數位通訊原理,兩門課完整涵蓋通訊基礎理論。 以下對通訊系統的課程內容做一簡介。於序論(1)之後,我們將複習關於訊號與系統之描述與分析的重要觀念(2-3)。接著介紹常用的類比調變方法,並討論如何接收這些信號(4-6),我們將會強調類比通訊的觀念和作法、是未來瞭解數位通訊的必要基礎,在例子的選擇上,也會著重對數位通訊延伸和比較。藉由介紹脈衝調變(7-8),我們逐步介紹從類比系統到數位系統的演進發展。接著介紹在無雜訊情況下的數位基頻通訊(9-10),這是最簡單的數位通訊型式,經由與類比通訊的比較,凸顯兩種方式的深刻區別但亦同時具有密切關係。雜訊干擾是通訊過程中重要的現象,我們必須了解其特性與描述方法。這些數學工具在隨機過程(11-14)主題之下討論之。(事實上,許多時候不但是雜訊,連訊號也適合用隨機過程來描述。) 我們使用這些工具探討雜訊對類比信號傳輸品質的影響(15-16),並進一步理解數位基頻通訊系統的相關議題(17)。最後總結,在更廣的系統架構下比較數位/類比系統的異同(15),建立更完整的通訊系統觀念。 本課程除了基礎理論的練習,也強調以電腦模擬來瞭解通訊系統的運作過程。因此對Matlab或C語言的熟練很重要,電腦模擬佔的比重也很可觀,請同學注意。
