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 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 کاملInterference Alignment Algorithm over Partially connected MIMO Interference Broadcast Channels Network
Conversely to the fully connected case, it has been proved in theory that interference alignment (IA) can be achievable in a partially connected multi-cell multiple input and multiple output (MIMO) interfering broadcast channels (IBC) network of arbitrary size efficiently. For this applicable significance, based on the L-interfering MIMO IBC model, we present three iterative IA algorithms to so...
متن کاملSettling the feasibility of interference alignment for the MIMO interference channel: the symmetric square case
Determining the feasibility conditions for vector space interference alignment in the K-user MIMO interference channel with constant channel coefficients has attracted much recent attention yet remains unsolved. The main result of this paper is restricted to the symmetric square case where all transmitters and receivers have N antennas, and each user desires d transmit dimensions. We prove that...
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...
