Rayleigh Fading

Rayleigh fading is a phenomenon that affects wireless signals as they travel through the environment. It occurs when multiple scattered signal paths, caused by objects like buildings and trees, combine at the receiver. These varying paths create interference, causing the signal strength to fluctuate unpredictably. This fading is named after the Rayleigh distribution, which models these rapid variations in signal amplitude. It is common in environments without a direct line-of-sight, impacting the quality and reliability of wireless communications, especially in urban or densely built areas.
