About Fading - Keysight

WebAbout Fading. A transmitted signal undergoes changes while traveling through the propagation path to the receiver. The effect of these changes is commonly called fading. In free-space, a signal follows one path and arrives at the receiver with little attenuation. This is not the case for a signal that encounters obstacles in the propagation path. Webprovides superior performance to Rayleigh fading. The probability of having line-of-sight (LOS) component depends on the size of the cell. The smaller the cell the higher the probability of having LOS path. If there is no dominant path then the Rician pdf reduces to Rayleigh pdf. When A is large church benches for sale ebay
