數位通訊原理

這是銜接通訊原理(類比通訊)的初階數位通訊系統課程。自數十年前起,通訊系統逐漸由採用類比訊號傳輸的方式轉換為採用數位訊號傳輸。歷經多年,通訊系統與無線通訊標準仍在演進中。本課程介紹數位通訊的基礎理論。課程重點在數位訊號傳輸的技術,特別是在探討一個位元(bit)在傳輸過程中,如何透過傳送端的調變設計與接收端的解碼器設計來達成某種效能的最佳化,如最小錯誤率之設計。在整個通訊系統中,這類技術或被稱為實體層(PHY層)技術。(務請注意本課箵所需的先備能力。) This is a fundamental digital communication system course, which intends to be a sequel to the first communication systems (analog communications) course. The progress from analog communication to digital communication, while started decades ago, is still evolving. This course introduces to the students the fundamental theory and current practices of digital communication systems. The focus is on the technologies applied to digital signal transmission. We start from the simple binary bits transmissions from a single transmitter to a single receiver, and we look into the designs of transmitter/receiver that achieves the optimality for certain preferred system performance, such as minimum bit error rate. The approaches discussed here are sometimes referred to as the physical layer (PHY layer) technologies in the overall data communication system. (Please check the prerequisites.)
