Strong Data Processing Inequalities for Input Constrained Additive Noise Channels
Flavio P. Calmon, Yury Polyanskiy, Yihong Wu
This paper quantifies the intuitive observation that adding noise reduces available information by means of non-linear strong data processing inequalities. Consider the random vari…
Strong data-processing inequalities for channels and Bayesian networks
Yury Polyanskiy, Yihong Wu
The data-processing inequality, that is, for a Markov chain , has been the method of choice for proving impossibility (converse) results in infor…
Minimum Energy to Send Bits Over Multiple-Antenna Fading Channels
Wei Yang, Giuseppe Durisi, Yury Polyanskiy
This paper investigates the minimum energy required to transmit information bits with a given reliability over a multiple-antenna Rayleigh block-fading channel, with and withou…
Wasserstein continuity of entropy and outer bounds for interference channels
Yury Polyanskiy, Yihong Wu
It is shown that under suitable regularity conditions, differential entropy is a Lipschitz functional on the space of distributions on -dimensional Euclidean space with respect…
Joint source-channel coding with feedback
Victoria Kostina, Yury Polyanskiy, Sergio Verdú
This paper quantifies the fundamental limits of variable-length transmission of a general (possibly analog) source over a memoryless channel with noiseless feedback, under a distor…
