摘要
随着通信技术日新月异的发展,我们已经进入了数字化时代,由于压缩技术的应用,高质量、大容量的数字传输发射系统必将取代原有的模拟系统。所要探讨的就是微波电路数字化传输部分,从数字微波发射机和收信机单元结构入手,着重介绍自动发信功率控制,自适应均衡,最后介绍天馈线系统及分集技术。
With the rapid development of communication technology, the human society has already entered the digital time. The high-quality and large-capacity digital transmission system will replace the analog system because of the application of compression technology. The paper discusses the digitalized transmission part of microwave circuit. Firstly the cell structure of digital microwave transmitter-receiver is analyzed, then the adaptive transmitter power control and adaptive equalization are introduced on emphasis, and finally the antenna-feeder system and diversity technique are introduced.
