**课程总结：数字通信基础** 本课程“数字通信基础”深入探讨了数字通信在现代电子世界中的关键作用。课程首先阐述了数字通信的定义，即通过点对点或点对多点通信信道进行数据的物理传输，以及其处理离散消息的特性。 课程强调了数字通信相比传统模拟通信的优势，指出模拟信号在长距离传输中存在失真、干扰和安全漏洞等问题。为了克服这些挑战，本课程将重点介绍将信号数字化的技术，以及数字化的必要性，从而实现更清晰、准确且无损的通信。 通过本课程的学习，学员将全面理解数字通信的构成组件，掌握信息论的基本原理，理解信道编码、熵的概念，并熟悉各种调制技术和扩频通信。本课程旨在帮助学生建立对数字通信核心概念的深刻理解，为他们在数字化时代有效进行信息交流奠定坚实基础。
Digital communication has proliferated in a big way in the previous years. Digital communication is the physical transfer of data over Point-To-Point or Point-To-Multipoint communication channel. It is transfer of discrete messages. Digital communication plays a vital role in today's electronic world. In digital communication the data transfer rate depends upon it's characteristics. Communications technology that intimidated many of us just a few years ago is now a part of everyday life. The conventional methods of communication used analog signals for long distance communications, which suffer from many losses such as distortion, interference, and other losses including security breach.In order to overcome these problems, the signals are digitized using different techniques. The digitized signals allow the communication to be more clear and accurate without losses. Digital communication is the process of devices communicating information digitally. This course will help students to get a good idea on how the signals are digitized and why digitization is needed. By the completion of this course, the student will be able to understand the conceptual details involved in digital communication.In this course, students will be able to learn some essential things about Digital Communications like components, Information Theory, Channel Coding, Entropies, Modulation Techniques, Spread Spectrum Communication.
