State-Dependent Channels with a Message-Cognizant Helper
Amos Lapidoth, Ligong Wang, Yiming Yan
The capacity of a state-dependent discrete memoryless channel (SD-DMC) is derived for the setting where a message-cognizant rate-limited helper observes the state sequence noncausa…
The characteristic polynomials of uniform hypercycles with length four
Cunxiang Duan, Ligong Wang, Yulong Wei
Let be a cycle with length The -uniform hypercycle with length obtained by adding new vertices in every edge of denoted by In this pap…
Covert Communication over Two Types of Additive Noise Channels
Cécile Bouette, Laura Luzzi, Ligong Wang
We extend previous results on covert communication over the additive white Gaussian noise channel to two other types of additive noise channels. The first is the Gaussian channel w…
Private-Capacity Bounds for Bosonic Wiretap Channels
Ligong Wang, Jeffrey H. Shapiro, Nivedita Chandrasekaran +1
We prove an upper bound on the private capacity of the single-mode noiseless bosonic wiretap channel. Combined with a previous lower bound, we obtain the low photon-number asymptot…
