Preface

Since the 21st century, the development of science and technology promotes the rapid improvement of the level of science and technology. In the field of communication, with the changes of the times, mobile communication technology has developed rapidly from low-level mobile communication technology to high-level modern mobile communication technology after technological innovation and development. At present, with the popularity of the Internet and technological innovation, China is in a period of rapid development of new generation information technology such as Internet, big data, artificial intelligence and regional chain, which promotes the continuous innovation and improvement of modern mobile communication technology.
  At the same time, digital communication has become an important means of information transmission. With the global digitization has become the main trend of today’s society, the continuous emergence of new digital communication equipment, people have become increasingly inseparable from the means of digital communication,and more and more expect to understand and master digital communication technology. It can be predicted that big data and artificial intelligence (AI) will have a profound impact on all aspects of society in the future. In the face of the future wireless communication super heterogeneous network, a variety of communication scenarios, a large number of antenna units, large bandwidth, new service requirements, using big data technology or data-driven and artificial intelligence is undoubtedly the inevitable choice.

前 言

21 世纪以来，科技的发展促进科技水平的快速提升，在通信领域里移动通信技术随着时代的变迁，经过一次次技术性创新发展，从起初低水平移动通信技术快速发展成为高水平的现代移动通信技术。当前，随着互联网的普及以及技术创新，中国正处于互联网、大数据、人工智能以及区域链等新一代信息技术高速发展时期，促使现代移动通信技术在不断创新和完善。
       同时，数字通信已成为信息传输的重要手段。随着全球数字化已成为当今社会的主要潮流，数字通信新设备的不断涌现，人们已经越来越离不开数字通信这种手段， 并且越来越期望了解和掌握数字通信技术。 可以预见， 未来大数据与人工智能(将深刻影响社会的方方面面。面对未来无线通信超异构网络、多种通信场景、大量天线单元、大带宽、新的服务需求，采用大数据技术或数据驱动和人工智能无疑是必然选择。
