On the Feasibility of Interference Alignment for the K-User MIMO Channel with Constant Coefficients
In this paper, we consider the feasibility of linear interference alignment (IA) for multiple-input multiple-output (MIMO) channels with constant coefficients for any number of users, antennas and streams per user. We combine algebraic geometry techniques with differential topology ones and prove much stronger results than those previously published on this topic. Specifically, we consider the ...
متن کاملOn Optimality of Linear Interference Alignment for the Three-User MIMO Interference Channel with Constant Channel Coefficients
We investigate the optimality of linear interference alignment (allowing symbol extensions) for 3-user MT × MR MIMO interference channel where MT and MR denote the number of antennas at each transmitter and each receiver, respectively, and the channel coefficients are held constant. Recently, Wang et al. have conjectured that interference alignment based on linear beamforming using only proper ...
متن کاملOn the Number of Interference Alignment Solutions for the K-User MIMO Channel with Constant Coefficients
In this paper, we study the number of different interference alignment (IA) solutions in a K -user multiple-input multiple-output (MIMO) interference channel, when the alignment is performed via beamforming and no symbol extensions are allowed. We focus on the case where the number of IA equations matches the number of variables. In this situation, the number of IA solutions is finite and const...
متن کاملPartial Interference Alignment for K-user MIMO Interference Channels
In this paper, we consider a Partial Interference Alignment and Interference Detection (PIAID) design for K-user quasi-static MIMO interference channels with discrete constellation inputs. Each transmitter has M antennas and transmits L independent data streams to the desired receiver with N receive antennas. We focus on the case where not all K − 1 interfering transmitters can be aligned at ev...
متن کاملAdaptive limited feedback for interference alignment in MIMO interference channels
It is very important that the radar sensor network has autonomous capabilities such as self-managing, etc. Quite often, MIMO interference channels are applied to radar sensor networks, and for self-managing purpose, interference management in MIMO interference channels is critical. Interference alignment (IA) has the potential to dramatically improve system throughput by effectively mitigating ...
