随着科学技术的不断发展,移动通信领域也在快速发展,第一代与第二代移动通信系统已经不能满足日益增长的需求,第三代移动通信系统也不能适应移动通信系统的发展速度,为了实现移动通信技术的提高,第四代移动通信系统随之产生,文中将对第四代移动通信系的概况统进行介绍,对第四代移动通信系统的关键技术进行阐述。
With the continuous development of science and technology, the field of mobile communications is also rapidly developing. The first generation and the second generation of mobile communication systems can no longer meet the growing demand. The third generation of mobile communication systems can not meet the requirements of mobile communication systems. In order to improve the mobile communication technology, the fourth generation of mobile communication system is generated. The article will introduce the overview of the fourth generation of mobile communication system and the key technologies of the fourth generation of mobile communication system.
