In a very sluggish-fading channel, it is actually not possible to work with time diversity as the transmitter sees only a single realization from the channel inside its hold off constraint. A deep fade as a result lasts the whole length of transmission and cannot be mitigated utilizing coding.
In a quick-fading channel, the transmitter may well benefit from the variations in the channel circumstances applying time range to assist improve robustness from the interaction to A brief deep fade. Even though a deep fade may quickly erase a few of the data transmitted, use of an error-correcting code coupled with properly transmitted bits in the course of other time instances (interleaving) can let to the erased bits to become recovered.
