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…
Integer Forcing: Effective SNR Distribution and Practical Block-Based Schemes
Ron Meiry, Omer Gurewitz, Asaf Cohen
Integer Forcing (IF) is a novel linear receiver architecture, where instead of separating the codewords sent by each transmitter, and decoding them individually, forces integer-val…
On Secrecy Rates and Outage in Multi-User Multi-Eavesdroppers MISO Systems
Joseph Kampeas, Asaf Cohen, Omer Gurewitz
In this paper, we study the secrecy rate and outage probability in Multiple-Input-Single-Output (MISO) Gaussian wiretap channels at the limit of a large number of legitimate users…
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…
