What is outage in wireless communication?

Outage probability is defined as the point at which the receiver power value falls below the threshold (where the power value relates to the minimum signal to noise ratio (SNR) within a cellular), one can say that the receiver is out of the range of BS in cellular communications.

What is outage capacity?

The outage capacity is defined as the maxi- mum data rate that can be achieved given a specified outage probability, i.e. the probability that a signal is not properly decoded.

How do you calculate probability of outage?

For slow fading channel, outage probability = P(C < r) = P(log2(1 + h2 SNR) < r), where r is the required threshold information rate.

What is ergodic capacity?

Abstract: Ergodic capacity is an important performance measure associated with reliable communication at the highest rate at which information can be sent over the channel with a negligible probability of error.
