Correction to "Private Information Retrieval Over Gaussian MAC"
Or Elimelech, Ori Shmuel, Asaf Cohen
In the above article \cite{shmuel2021private}, the authors introduced a PIR scheme for the Additive White Gaussian Noise (AWGN) Multiple Access Channel (MAC), both with and without…
Compute-and-Forward in Large Relaying Systems: Limitations and Asymptotically Optimal Scheduling
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Compute and Forward (CF) is a coding scheme which enables receivers to decode linear combinations of simultaneously transmitted messages while exploiting the linear properties of l…
Private Information Retrieval Over Gaussian MAC
Ori Shmuel, Asaf Cohen
Consider the problem of Private Information Retrieval (PIR), where a user wishes to retrieve a single message from non-communicating and non-colluding databases (servers). All…
Multi-Antenna Jamming in Covert Communication
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Covert communication conceals transmission of messages from Alice to Bob out of a watchful adversary, Willie, who tries to determine if a transmission took place or not. While cove…
Asymptotically Optimal Scheduling for Compute-and-Forward
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Consider a Compute and Forward (CF) relay network with users and a single relay. The relay tries to decode a linear function of the transmitted signals. For such a network, let…
Distributed Scheduling in Time Dependent Environments: Algorithms and Analysis
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Consider the problem of a multiple access channel in a time dependent environment with a large number of users. In such a system, mostly due to practical constraints (e.g., decodin…
The Necessity of Scheduling in Compute-and-Forward
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Compute and Forward (CF) is a promising relaying scheme which, instead of decoding single messages or forwarding/amplifying information at the relay, decodes linear combinations of…
Capacity and performance analysis for multi-user system under distributed opportunistic scheduling in a time dependent channel
Ori Shmuel, Asaf Cohen, Omer Gurewitz
Consider the problem of a multi-user multiple access channel. While several multi-user coding techniques exist, in practical scenarios, not all users can be scheduled simultaneousl…
