Interference alignment (IA) with symbol extensions in the quasi-static flat-fading K-user multipleinput multiple-output (MIMO) interference channel (IC) is considered in this paper. In general, long symbol extensions are required to achieve the optimal fractional degrees of freedom (DOF). However, long symbol extensions over orthogonal dimensions produce structured (diagonal or block diagonal) channel...
In this paper, interference alignment (IA) achieved from one side is considered in the K-user constant multiple-input multiple-output (MIMO) interference channel (IC). Different from most existing algorithms which need alternating between the transmitter and receiver, our algorithm runs at transmitters only, thereby avoiding vast information exchanged between the transmitter and receiver. The essential...
Interference alignment(IA) with symbol extensions in the K-user multiple-input multiple-output (MIMO) interference channel(IC) is considered in this paper. Symbol extensions produce the channels of special structure. Most of existing approaches are limited in cases where the channels have some special structure, because they align the interference without preserving the dimensionality of the desired...
