1 引言军事通信要数字化是不言而喻的,因为军事通信的保密要求很高,民用通信已经很快数字化了,军事通信理应走在前头。可是,移动通信的数字化为什么要晚一些呢?这是因为移动通信的环境远较固定通信恶劣,它必须克服环境变化所造成的各种障碍,才能完成数字化的任务。本文就移动通信数字化的关键技术予以讨论。
1 INTRODUCTION It is self-evident that military communications should be digitized because of the high requirements for the confidentiality of military communications, the rapid digitization of civilian communications, and the advancement in military communications. However, why should the digitalization of mobile communications occur later? This is because the environment of mobile communications is far worse than that of fixed communications. It must overcome various obstacles caused by changes in the environment in order to complete the digital task. This article discusses the key technologies of digitalization in mobile communications.
