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. The coherence time is a measure of the minimum time required for the magnitude change or phase change of the channel to become uncorrelated from its previous value. • Slow fading arises when the coherence time of the channel is large relative to … Webbslow fading overload margin is Lslow = 14 dB, and 2% fast fading overload margin is Lfast = 7 dB. The receiver sensitivity is -104 dBm (dBm: dB with respect to a 1 mW reference). Calculate the transmitter power.
