基于LTE技术的战术通信系统研究进展

概述了民用移动通信发展过程，总结了LTE技术的技术优势和发展前景，提出了利用LTE技术同步发展战术通信的新思想。目前战术通信已经不能满足多媒体业务发展的需求，逐步向着高速化、宽带化和网络化方向发展，美国战术通信发展很快，民用技术的军用化扮演了重要角色。LTE技术符合战术通信的发展方向，但也存在移动性差、电波衰落大等问题，通过采用频率下移变换、小型化设计等技术，可以有效解决这些问题。利用LTE技术发展无线宽带战术通信具有十分重要意义，可以极大推动战术通信的发展，使战术通信发生根本性变革、跨越式发展。

Development progress of LTE-based tactical communications system

The development process of civilian mobile communications is overviewed, the technical advantages and development prospects of the LTE technology are summarized, new ideas of the simultaneous development of tactical communication by use of LTE technology is presented. At present,tactical communications can no longer meet the needs of the development of multimedia services, and develop gradually toward the direction of the high-speed,broadband and network. U.S. tactical communications has developed rapidly,civil military has played an important role. LTE technology conforms the direction of development of tactical communications, but there are also poor mobility and the big decline of electromagnetic wave. Through the use of frequency conversion and miniaturization design, these problems can be effectively solved. Using LTE technology to develop new tactical communications has a very important significance,which can greatly promote the development of tactical communications, and make the tactical communications change fundamentally and realize leap frog development.
