On the Capacity and Degrees of Freedom Regions of MIMO Interference Channels with Limited Receiver Cooperation
This paper gives the approximate capacity region of a two-user MIMO interference channel with limited receiver cooperation, where the gap between the inner and outer bounds is in terms of the total number of receive antennas at the two receivers and is independent of the actual channel values. The approximate capacity region is then used to find the degrees of freedom region. For the special ca...
متن کاملDegrees of Freedom for Instantaneous-Relay Aided Interference Channel: Bounds and Achievable Schemes
The K-user flat fading MIMO interference channel with J instantaneous relays (KICJR) is considered. In the KICJR, the effective channel between sources and destinations including the relays has certain structure and is non-generic. For non-generic channels, the achievable degrees of freedom (DoF) is still unknown. Lee and Wang showed that by using the aligned interference neutralization scheme ...
متن کاملDegrees of Freedom Region for the MIMO X Channel
We provide achievability as well as converse results for the degrees of freedom region of a MIMO X channel, i.e., a system with two transmitters, two receivers, each equipped with multiple antennas, where independent messages need to be conveyed over fixed channels from each transmitter to each receiver. The inner and outerbounds on the degrees of freedom region are tight whenever integer degre...

متن کاملInterference Alignment and the Degrees of Freedom for the 3 User Interference Channel
We explore the degrees of freedom region for the 3 user wireless interference channel with perfect channel knowledge at all nodes. While the best known outerbound for the K user interference channel states that there cannot be more than K/2 degrees of freedom, it has been conjectured that in general the constant interference channel with any number of users has only one degree of freedom. We sh...
