The Poisson Channel at Low Input Powers
Amos Lapidoth, Jeffrey H. Shapiro, Vinodh Venkatesan +1
The asymptotic capacity at low input powers of an average-power limited or an average- and peak-power limited discrete-time Poisson channel is considered. For a Poisson channel who…
Multipath Channels of Unbounded Capacity
Tobias Koch, Amos Lapidoth
The capacity of discrete-time, noncoherent, multipath fading channels is considered. It is shown that if the variances of the path gains decay faster than exponentially, then capac…
On the Capacity of Free-Space Optical Intensity Channels
Amos Lapidoth, Stefan M. Moser, Michele A. Wigger
New upper and lower bounds are presented on the capacity of the free-space optical intensity channel. This channel is characterized by inputs that are nonnegative (representing the…
The Gaussian MAC with Conferencing Encoders
Shraga I. Bross, Amos Lapidoth, Michele A. Wigger
We derive the capacity region of the Gaussian version of Willems's two-user MAC with conferencing encoders. This setting differs from the classical MAC in that, prior to each trans…
On Multipath Fading Channels at High SNR
Tobias Koch, Amos Lapidoth
This paper studies the capacity of discrete-time multipath fading channels. It is assumed that the number of paths is finite, i.e., that the channel output is influenced by the pre…
A Channel that Heats Up
Tobias Koch, Amos Lapidoth, Paul P. Sotiriadis
Motivated by on-chip communication, a channel model is proposed where the variance of the additive noise depends on the weighted sum of the past channel input powers. For this chan…
