On the Interference Alignment Designs for Secure Multiuser MIMO Systems
In this paper, we propose two secure multiuser multiple-input multiple-output transmission approaches based on interference alignment (IA) in the presence of an eavesdropper. To deal with the information leakage to the eavesdropper as well as the interference signals from undesired transmitters (Txs) at desired receivers (Rxs), our approaches aim to design the transmit precoding and receive sub...
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 کاملReal Interference Alignment
In this paper, we show that the total Degrees-OfFreedoms (DOF) of the K-user Gaussian Interference Channel (GIC) can be achieved by incorporating a new alignment technique known as real interference alignment. This technique compared to its ancestor vector interference alignment performs on a single real line and exploits the properties of real numbers to provide optimal signaling. The real int...
متن کاملBlind Fractional Interference Alignment
Fractional Interference Alignment (FIA) is a transmission scheme which achieves any value between [0,1] for the Symbols transmitted per Antenna per Channel use (SpAC). FIA was designed in [1] specifically for Finite Alphabet (FA) signals, under the constraint that the Minimum Distance (MD) detector is used at all the receivers. Similar to classical interference alignment, the FIA precoder also ...
متن کاملInterference Alignment for DSL.dvi
Inter-line interference, known as crosstalk, is the most significant source of performance degradation for Digital Subscriber Line (DSL) systems. Vectored DSL is an effective technique for the elimination of crosstalk; however, there are many scenarios in which Vectored DSL is not implementable or practical. Interference alignment is presented as a technique to solve these issues. In particular...
