ergodic capacity
Hi
In statistical channel like fading channel, when capacity is computed, it depend on channel statistic(channel coefficient). So it is random variable. Because of that, expected value of capacity should be computed.
Relation between capacity and channel coefficient is not linear, so computing expected valu is not easy.
If channel is Ergodic, expected value computed in time and this is Ergodic capacity.
Another form of capacity in statistical channel is Outage capacity.
