On the Feedback Capacity of the Fully Connected -User Interference Channel
Soheil Mohajer, Ravi Tandon, H. Vincent Poor
The symmetric K user interference channel with fully connected topology is considered, in which (a) each receiver suffers interference from all other (K-1) transmitters, and (b) ea…
On the Symmetric Feedback Capacity of the K-user Cyclic Z-Interference Channel
Ravi Tandon, Soheil Mohajer, H. Vincent Poor
The K-user cyclic Z-interference channel models a situation in which the kth transmitter causes interference only to the (k-1)th receiver in a cyclic manner, e.g., the first transm…
Capacity Region of Vector Gaussian Interference Channels with Generally Strong Interference
Xiaohu Shang, H. Vincent Poor
An interference channel is said to have strong interference if for all input distributions, the receivers can fully decode the interference. This definition of strong interference…
Noisy-Interference Sum-Rate Capacity for Vector Gaussian Interference Channels
Xiaohu Shang, H. Vincent Poor
New sufficient conditions for a vector Gaussian interference channel to achieve the sum-rate capacity by treating interference as noise are derived, which generalize the existing r…
