COMPUTER FUNDAMENTALS

Detailed explanation-1: -Fading does not occur when mobile receiver is stationary. Explanation: The received signal may fade even when the mobile receiver is stationary. It is due to the movement of surrounding objects in the radio channel.

Detailed explanation-2: -In wireless communications, fading is variation of the attenuation of a signal with various variables. These variables include time, geographical position, and radio frequency. Fading is often modeled as a random process.

Detailed explanation-3: -Explanation: Slow fading channel may be assumed to be static over one or several reciprocal bandwidth intervals. In the frequency domain, this implies that the Doppler spread of the channel is much less than the bandwidth of the baseband signals.

Detailed explanation-4: -Interference fading is also a result of the multipath propagation of signals transmitted from the antenna. It occurs when waves interfere at the channel while propagating from an end to another.

Detailed explanation-5: -propagation paths can produce severe fading at the receiver. Fading occurs when there are significant variations in received signal amplitude and phase over time or space. Fading can be frequency-selective-that is, different frequency components of a single transmitted signal can undergo different amounts of fading.
