Interference Alignment for the K-user Interference Channel with Imperfect CSI
In this paper we explore the information-theoretic aspects of interference alignment and its relation to channel state information (CSI). For the K−user interference channel using different changing patterns between different users, we propose several methods to align some parts of interferences and to increase what is achieved by time sharing method. For more practical case when all the channe...
متن کاملEE360 project: Interference Alignment for MIMO interference channel using Imperfect CSI
Interference alignment is a novel technique introduced in [1] that allows for K/2 degrees of freedom in a K-user interference channel. A related work [2] proves the achievability of 4/3 degrees of freedom on the 2 user MIMO-X channel. However, the techniques require Channel State Information (CSI) at transmitter. In [3], it is shown that M(L− 1) log P bits of feedback broadcased by each Rx to a...
متن کاملReal - Time Distributed Implementation of Interference Alignment with Analog Feedback
Interference alignment (IA) is known to achieve the maximum capacity for the interference channel. IA is a precoding technique to make interfering signals be aligned at receivers. The resulting sum rate is linearly scaled with the number of users. The performance of IA, however, depends on the practical issues such as the performance of synchronization, channel estimation and feedback. In this ...
متن کاملInterference 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 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...
