A Coordinate System for Gaussian Networks [PDF]
, 2010 This paper studies network information theory problems where the external noise is Gaussian distributed. In particular, the Gaussian broadcast channel with coherent fading and the Gaussian interference channel are investigated.

Quantum Capacities of Bosonic Channels [PDF]
, 2006 We investigate the capacity of bosonic quantum channels for the transmission of quantum information. Achievable rates are determined from measurable moments of the channel by showing that every channel can asymptotically simulate a Gaussian channel which

Some New Results on the GaussianWiretap Feedback Channel
Entropy, 2019 In this paper, the Gaussian wiretap feedback channel is revisited, and some new resultson its secrecy capacity are obtained. To be specific, first, we show that the Schalkwijk−Kailath (SK)feedback scheme, which achieves the secrecy capacity of the ...

Symplectic dilations, Gaussian states and Gaussian channels [PDF]
Indian Journal of Pure and Applied Mathematics, 2015 By elementary matrix algebra we show that every real $2n \times 2n$ matrix admits a dilation to an element of the real symplectic group $Sp (2(n+m))$ for some nonnegative integer $m.$ Our methods do not yield the minimum value of $m,$ for which such a dilation is possible. After listing some of the main properties of Gaussian states in $L^2 (\mathbb{R}^

The Gaussian Multiple Access Diamond Channel [PDF]
, 2015 In this paper, we study the capacity of the diamond channel. We focus on the special case where the channel between the source node and the two relay nodes are two separate links with finite capacities and the link from the two relay nodes to the ...

Inner and Outer Bounds for the Gaussian Cognitive Interference Channel and New Capacity Results [PDF]
, 2010 The capacity of the Gaussian cognitive interference channel, a variation of the classical two-user interference channel where one of the transmitters (referred to as cognitive) has knowledge of both messages, is known in several parameter regimes but ...

Using a Gaussian channel Twice [PDF]
2013 IEEE International Symposium on Information Theory, 2013 The problem of communicating one bit over a memoryless Gaussian channel with an energy constraint is discussed. It is assumed that the channel is allowed to be used only two times. An ideal feedback channel is also supposed available. The optimal feedback strategy and the bit-error probability are derived.

Additivity properties of a Gaussian channel [PDF]
Physical Review A, 2004 The Amosov-Holevo-Werner conjecture implies the additivity of the minimum Re'nyi entropies at the output of a channel. The conjecture is proven true for all Re'nyi entropies of integer order greater than two in a class of Gaussian bosonic channel where the input signal is randomly displaced or where it is coupled linearly to an external environment.
