Information Velocity of Cascaded Gaussian Channels with Feedback
Elad Domanovitz, Anatoly Khina, Tal Philosof +1
We consider a line network of nodes, connected by additive white Gaussian noise channels, equipped with local feedback. We study the velocity at which information spreads over this…
Modulation and Estimation with a Helper
Anatoly Khina, Neri Merhav
The problem of transmitting a parameter value over an additive white Gaussian noise (AWGN) channel is considered, where, in addition to the transmitter and the receiver, there is a…
The Information Velocity of Packet-Erasure Links
Elad Domanovitz, Tal Philosof, Anatoly Khina
We consider the problem of in-order packet transmission over a cascade of packet-erasure links with acknowledgment (ACK) signals, interconnected by relays. We treat first the case…
Energy-limited Joint Source--Channel Coding via Analog Pulse Position Modulation
Omri Lev, Anatoly Khina
We study the problem of transmitting a source sample with minimum distortion over an infinite-bandwidth additive white Gaussian noise channel under an energy constraint. To that en…
Universal Joint Source-Channel Coding Under an Input Energy Constraint
Omri Lev, Anatoly Khina
We consider the problem of transmitting a source over an infinite-bandwidth additive white Gaussian noise channel with unknown noise level under an input energy constraint. We cons…
Causal Posterior Matching and its Applications
Anusha Lalitha, Anatoly Khina, Tara Javidi
We consider the problem of communication over the binary symmetric channel with feedback, where the information sequence is made available in a causal, possibly random, fashion. We…
Real-Time Variable-to-Fixed Lossless Source Coding of Randomly Arriving Symbols
Uri Abend, Anatoly Khina
We address the recently suggested problem of causal lossless coding of a randomly arriving source samples. We construct variable-to-fixed coding schemes and show that they outperfo…
Gauss-Markov Source Tracking with Side Information: Lower Bounds
Omri Lev, Anatoly Khina
We consider the problem of causal source coding and causal decoding of a Gauss--Markov source, where the decoder has causal access to a side-information signal. We define the infor…
Tracking and Control of Gauss-Markov Processes over Packet-Drop Channels with Acknowledgments
Anatoly Khina, Victoria Kostina, Ashish Khisti +1
We consider the problem of tracking the state of Gauss-Markov processes over rate-limited erasure-prone links. We concentrate first on the scenario in which several independent pro…
(Almost) Practical Tree Codes
Anatoly Khina, Wael Halbawi, Babak Hassibi
We consider the problem of stabilizing an unstable plant driven by bounded noise over a digital noisy communication link, a scenario at the heart of networked control. To stabilize…
Layered Uplink Transmission in Clustered Cellular Networks
Anatoly Khina, Tal Philosof, Moshe Laifenfeld
The demand for higher data rates and the scarce spectrum resources drive the adoption of collaborative communication techniques. In this work we shown that the existing cluster bas…
The Dirty MIMO Multiple-Access Channel
Anatoly Khina, Yuval Kochman, Uri Erez
In the scalar dirty multiple-access channel, in addition to Gaussian noise, two additive interference signals are present, each known non-causally to a single transmitter. It was s…
The MIMO Wiretap Channel Decomposed
Anatoly Khina, Yuval Kochman, Ashish Khisti
The problem of sending a secret message over the Gaussian multiple-input multiple-output (MIMO) wiretap channel is studied. While the capacity of this channel is known, it is not c…
Joint Unitary Triangularization for Gaussian Multi-User MIMO Networks
Anatoly Khina, Idan Livni, Ayal Hitron +1
The problem of transmitting a common message to multiple users over the Gaussian multiple-input multiple-output broadcast channel is considered, where each user is equipped with an…
Space-Time MIMO Multicasting
Idan Livni, Anatoly Khina, Ayal Hitron +1
Multicasting is the general method of conveying the same information to multiple users over a broadcast channel. In this work, the Gaussian MIMO broadcast channel is considered, wi…
Modulation for MIMO Networks with Several Users
Anatoly Khina, Ayal Hitron, Uri Erez
In a recent work, a capacity-achieving scheme for the common-message two-user MIMO broadcast channel, based on single-stream coding and decoding, was described. This was obtained v…
Physical-Layer MIMO Relaying
A. Khina, Y. Kochman, U. Erez
The physical-layer network coding (PNC) approach provides improved performance in many scenarios over "traditional" relaying techniques or network coding. This work addresses the g…
Joint Unitary Triangularization for MIMO Networks
Anatoly Khina, Yuval Kochman, Uri Erez
This work considers communication networks where individual links can be described as MIMO channels. Unlike orthogonal modulation methods (such as the singular-value decomposition)…
