Improved Random-Binning Exponent for Distributed Hypothesis Testing
Yuval Kochman, Ligong Wang
Consider the problem of distributed binary hypothesis testing with two terminals, where the decision is made at one of them (the "receiver"). We study the exponent of the error pro…
State-Dependent DMC with a Causal Helper
Amos Lapidoth, Ligong Wang
A memoryless state sequence governing the behavior of a memoryless state-dependent channel is to be described causally to an encoder wishing to communicate over said channel. Given…
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…
On the Capacity of MIMO Optical Wireless Channels
Longguang Li, Stefan M. Moser, Ligong Wang +1
This paper studies the capacity of a general multiple-input multiple-output (MIMO) free-space optical intensity channel under a per-input-antenna peak-power constraint and a total…
Capacity Results on Multiple-Input Single-Output Wireless Optical Channels
Stefan M. Moser, Ligong Wang, Michèle Wigger
This paper derives upper and lower bounds on the capacity of the multiple-input single-output free-space optical intensity channel with signal-independent additive Gaussian noise s…
Covert Communication with Channel-State Information at the Transmitter
Si-Hyeon Lee, Ligong Wang, Ashish Khisti +1
We consider the problem of covert communication over a state-dependent channel, where the transmitter has causal or noncausal knowledge of the channel states. Here, "covert" means…
