摘要
本文简要介绍了SDH数字微波传输系统中采用的几 项关键技术:高性能高速多状态调制解调技术;自 适应交叉极化干扰抵消技术;前向纠错技术;自适 应对抗多径衰落技术;自适应发信功率控制技术。
In this paper, we'll talk about some key technologies in microwave SDH: multi-level coding modulation; adaptive cross-polarization interference canceler; forward error correction; adaptive time domain equalizer and automatic transmit power control.
