Sentence examples for channel outage from inspiring English sources

Channel outage occurs if the capacity is less than the transmission rate R, where R is the desired spectral efficiency in bits/s/Hz.

Most of the works considering such an issue, however, focus on theoretical performance limits based on capacity and channel outage probability, as in [13 17].

We analyze the ergodic capacity and channel outage probability for a composite MIMO channel model, which includes both fast fading and shadowing effects.

The ergodic capacity and exact channel outage probability with space-time water-filling can be evaluated through numerical integrations, which can be further simplified by using approximated empirical eigenvalue and maximal eigenvalue distribution of MIMO fading channels.

For MIMO channels with large shadowing effects, however, space-time water-filling achieves significantly higher capacity per antenna than spatial water-filling at low to moderate SNR regimes, but with a much higher channel outage probability.

In fact, in more sophisticated MAC schemes, the probability of transmission at a node can be modeled as a function of general parameters, such as queuing statistics, the queue-dropping rate, the channel outage probability incurred by fading [24], the adaptation of the sampling to rate to patient's condition [25], the MAC strategy used [26], etc.

The link adaptation controller is aware 2 of the distribution of w. (Assumption 4) To cope with channel outages, the link adaptation controller applies a power back-off strategy to determine the transmission rate.

This analysis is somewhat different from that given in a recent article [17] that studied outage probabilities under a number of approximations: (i) they did not consider all possible outage scenarios (for a full consideration see [14]), (ii) all channel outages are treated with the same transmit powers, the same average channel gains, and thus the same average channel SNRs.

In DF relay channels, outage analysis was performed in DF relay channels with two destinations in [11], where the use of network coding achieves full diversity with less bandwidth and energy.

For the Rayleigh fading channel, the outage probability is given and approximated at a high SNR in the following manner: P out γ i, j, k, R = Pr γ i, j, k < 2 R − 1 = 1 − exp − 2 R − 1 Γ i, j ≈ 2 R − 1 Γ i, j, (5).

Now consider the set of channels in outage, namely { h : D ( P 1 ( N ), h ) > D m a x } with a non-zero probability measure.
