Webb11 sep. 2024 · The Fading types are divided into large scale fading and small scale fading (multipath delay spread and doppler spread). Flat fading and frequency selecting fading are part of multipath fading where as fast fading and slow fading are part of doppler spread fading. What are the different types of small scale fading? WebbSlow fading can be caused by events such as shadowing, where a large obstruction such as a hill or large building obscures the main signal path between the transmitter and the receiver. The amplitude change caused by shadowing is often modeled using a log-normal distribution with a standard deviation according to the log-distance path loss model. phone law drivingWebbSlow vs. Fast Fading The terms slow and fast fading refer to the rate at which the magnitude and phase change imposed by the channel on the signal changes.
