Interference alignment for the MIMO interference channel
We study vector space interference alignment for the MIMO interference channel with no time or frequency diversity. We prove both necessary and sufficient conditions for alignment. In particular, we characterize the feasibility of alignment for the symmetric three-user channel where all transmitters have M antennas and all receivers have N antennas, as well as feasibility of alignment for the f...
متن کاملImproper Signaling on the Two-user SISO Interference Channel
On a single-input-single-out (SISO) interference channel (IC), conventional non-cooperative strategies encourage players selfishly maximizing their transmit data rates, neglecting the deficit of performance caused by and to other players. In the case of proper complex Gaussian noise, the maximum entropy theorem shows that the best-response strategy is to transmit with proper signals (symmetric ...
متن کاملAchievable Degrees of Freedom of the K-User SISO Interference Channel With Blind Interference Alignment Using Staggered Antenna Switching
In this letter, we present the first characterization for the achievable Degrees-of-Freedom (DoF) by Blind Interference Alignment (BIA) using staggered antenna switching in the K-user Gaussian Interference Channel. In such scheme, each transmitter is equipped with one conventional antenna and each receiver is equipped with one reconfigurable (multi-mode) antenna. Assuming that the channel is kn...
متن کاملInterference alignment-and-cancellation scheme based on Alamouti code for the three-user multi-input-multi-output interference channel
An interference alignment (IA) scheme for interference channels was recently proposed to achieve the maximum degrees of freedom (DoF). Although most studies of IA focus on network throughput, that is, DoF, reliability in terms of diversity order is also an important performance measure. In this study, interference cancellation (IC) scheme based on Alamouti code in the multi-access scenario is a...
متن کاملChannel Aided Interference Alignment
Interference alignment (IA) is a transmission strategy that attempts to exploit all degrees of freedom available at the transmitter or at the receiver in a multiuser channel. This paper proposes a new scheme named channel aided interference alignment. It makes use of the channel structure beside the linear interference alignment schemes to achieve the optimum degrees of freedom in a K user inte...
