The Effect of the Signal Fading on the Digital Microwave System and the Design of Anti-fading Measures

摘要

Aiming at the bad effect of the fading on the digital microwave communication system, the authors analyze the cause to produce the fading, its effecting mechanism and its result. They also correspondingly analyze the AGC circuit, the spare wave channel inversion, frequency diversity, space diversity set, anti-fading antenna, and the application and improvement of anti-fading measures such as anti-fading antenna and adaptive equalization techniques. They present the applicable rules of anti-fading measures, and the designing thought of anti-fading circuit in the form of flowchart which will be very beneficial to the construction and maintenance of digital microwave communication system.
