Key Countermeasures Against Selective Fading
- Valtolina R.
As the microwave industry adopts higher modulation schemes, effective countermeasures against selective fading become extremely important. Service providers are already deploying 1024 Quadrature Amplitude Modulation (1024 QAM) systems. And 4096 QAM is on the near horizon. These higher modulation schemes are much more sensitive to selective fading. This article provides a technical overview of the factors that affect maximum link length and the key countermeasures against selective fading. With this information, service providers will be better prepared to evaluate microwave systems.
