Sampling Large Data on Graphs
Ilan Shomorony, A. Salman Avestimehr
We consider the problem of sampling from data defined on the nodes of a weighted graph, where the edge weights capture the data correlation structure. As shown recently, using spec…
Linear Degrees of Freedom of the MIMO X-Channel with Delayed CSIT
David T. H. Kao, A. Salman Avestimehr
We study the degrees of freedom (DoF) of the multiple-input multiple-output X-channel (MIMO XC) with delayed channel state information at the transmitters (delayed CSIT), assuming…
Approximate Capacity Region of the Two-User MISO Broadcast Channels with Delayed CSIT
Alireza Vahid, Mohammad Ali Maddah-Ali, Amir Salman Avestimehr
We consider the problem of multiple-input single-output Broadcast Channels with Rayleigh fading where the transmitter has access to delayed knowledge of the channel state informati…
Blind MIMOME Wiretap Channel with Delayed CSIT
Sina Lashgari, Amir Salman Avestimehr
We study the Gaussian MIMOME wiretap channel where a transmitter wishes to communicate a confidential message to a legitimate receiver in the presence of eavesdroppers, while the e…
Binary Fading Interference Channel with No CSIT
Alireza Vahid, Mohammad Ali Maddah-Ali, Amir Salman Avestimehr +1
We study the capacity region of the two-user Binary Fading (or Erasure) Interference Channel where the transmitters have no knowledge of the channel state information. We develop n…
A Generalized Cut-Set Bound for Deterministic Multi-Flow Networks and its Applications
Ilan Shomorony, A. Salman Avestimehr
We present a new outer bound for the sum capacity of general multi-unicast deterministic networks. Intuitively, this bound can be understood as applying the cut-set bound to concat…
