We impose the practical constraint that the encoder be unaware of even the statistical dependencies between source and side information.
In this work, we will take the standard Gaussian measure as the reference measure and study the variation of optimal transport maps in Sobolev spaces with respect to it; as a by-product, an inequality which gives a precise link between the variation of entropy, Fisher information between source and target measures, with the Sobolev norm of the optimal transport map will be given.
In our system model, however, the use of time-division constrains the source to be silent half of the time which halves the mutual information but doubles the power, giving the mutual information between source and R i in the first phase as I s r i = 1 2 log 1 + 2 h s r i 2 ρ.
Thus, the mutual information between source and destination can be written as I sd = log(1 + ||h sd ||2ρ).
Outage probability is defined as Pout = P r{I < R} where I is the maximum average mutual information between source and destination and R is the spectral efficiency.
Similarly we can find the mutual information between source and i th relay as I s r i = log 1 + h s r i 2 ρ and the mutual information between i th relay and destination as I r i d = log 1 + h r i d 2 ρ.
If it's near impossible for sources to contact journalists securely because of mass surveillance – while already in a climate where whistleblowers are likely to be aggressively hunted down – we may see this flow of information between source and journalist run dry.
A widely acknowledged measurement of system security in WRNs is the maximal rate of secret information exchange between source and destination which is defined as secrecy capacity.
We define the outage probability as the probability that the mutual information I between source and destination falls below rate R, and this is denoted as Pr[I < R].
Professional literature and mainstream media are also suggested as avenues for the study of the relationship between writers, information sources, and information professionals.
