The Approximate Sum Capacity of the Symmetric Gaussian K-User Interference Channel
Approximate Sum Capacity the Symmetric Gaussian K-User Interference Channel Information Theory
2012/6/12
Interference alignment has emerged as a powerful tool in the analysis of multi-user networks. Despite considerable recent progress, the capacity region of the Gaussian K-user interference channel is s...
Improving Achievable Rate for the Two-User SISO Interference Channel with Improper Gaussian Signaling
Two-User SISO Interference Channel Improper Gaussian Signaling Information Theory
2012/5/24
This paper studies the achievable rate region of the two-user single-input-single-output (SISO) Gaussian interference channel, when the improper Gaussian signaling is applied. Under the assumption tha...
The DoF Region of the Multiple-Antenna Time Correlated Interference Channel with Delayed CSIT
The DoF Region the Multiple-Antenna Time Interference Channel Delayed CSIT Information Theory
2012/4/16
We consider the time-correlated multiple-antenna interference channel where the transmitters have (i) delayed channel state information (CSI) obtained from a latency-prone feedback channel as well as ...
An Outer Bound for the Memoryless Two-user Interference Channel with General Cooperation
Information Theory Memoryless Two-user Interference Channel General Cooperation Outer Bound
2012/4/16
The interference channel models a wireless network where several source-destination pairs compete for the same resources. When nodes transmit simultaneously the destinations experience interference. T...
Beamforming on the MISO interference channel with multi-user decoding capability
the MISO interference channel multi-user decoding capability Information Theory
2011/8/23
Abstract: This paper considers the multiple-input-single-output interference channel (MISO-IC) with interference decoding capability (IDC), so that the interference signal can be decoded and subtracte...

Interference channel Input correlation Binning scheme
2011/2/28
Allowing the input auxiliary random variables to be correlated and using the binning scheme, the Han-Kobayashi (HK) rate region for general interference channel is partially improved. The obtained par...
Aligned Interference Neutralization and the Degrees of Freedom of the 2x2x2 Interference Channel
Aligned Interference Neutralization Degrees of Freedom 2x2x2 Interference Channel
2011/1/20
We show that the 2 2 2 interference network, i.e., the multihop interference network formed by concatenation of two 2-user interference channels achieves the min-cut outer bound value of 2 DoF, fo...
Comments on Degrees of freedom region for $K$-user interference channel with $M$ antennas
Degrees of freedom region interference channel
2010/11/22
For a $K$-user interference channel with $M$ antenna at each transmitter and each receiver, the maximum total DoF of this channel has been previously determined to be $\max \sum_{k=1}^K d_k = MK/2$. H...
A Multi-Interference-Channel Matrix Pair Beamformer for CDMA Systems
Multi-Interference-Channel Matrix Pair Beamformer CDMA Systems
2010/12/16
Matrix pair beamformer (MPB) is a promising blind beamformer which exploits the temporal signature of the signal of interest (SOI) to acquire its spatial statistical information. It does not need any ...
The Capacity of the Semi-Deterministic Cognitive Interference Channel and its Application to Constant Gap Results for the Gaussian Channel
ThCapacity Semi-Deterministic Cognitive Interference Channel Application to Constant Gap Results
2010/12/7
The cognitive interference channel (C-IFC) consists of a classical two-user interference channel in which the message of one user (the “primary” user) is non-causally available at
the transmitter of ...
