Signal Fading

A transmitted signal changes as it travels to the receiver. The effect of these changes is commonly referred to as fading. The fading results from the superimposition of transmitted signals, in which differences in attenuation, delay and phase shift have occurred. Slow fading: In case shadow effect is caused by obstacles, and the receiving signal … Read more

Slow Fading Margin in LTE with example of standard deviations in slow fading

Shadow fading indicates the fading brought by obstruction due to a building or a natural feature. Shadow fading changes slowly, and is thus called “slow fading”. Statistics repeatedly show that the median levels of received signals follow log-normal distribution with the time and location at a certain distance. Fading caused by location (mainly from obstruction) … Read more
