Improvement of the Han-Kobayashi Rate Region for General Interference Channel-v2
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 ...
