Gaussian Wiretap Channel With Amplitude and Variance Constraints
IEEE Transactions on Information Theory(2015)
摘要
We consider the Gaussian wiretap channel with amplitude and variance constraints on the channel input. We first show that the entire rate-equivocation region of the Gaussian wiretap channel with an amplitude constraint is obtained by discrete input distributions with finite support. We prove this result by considering the existing single-letter description of the rate-equivocation region, and show...
