Interference Alignment: Practical Challenges and Test-bed Implementation
Data traffic over wireless communication networks has experienced a tremendous growth in the last decade, and it is predicted to exponentially increase in the next decades [1]. Enabling future wireless networks to fulfill this expectation is a challenging task both due to the scarcity of radio resources (e.g. spectrum and energy), and also the inherent characteristics of the wireless transmissi...

15 صفحه اولInterference 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 کاملPractical Challenges of Enterprise Modeling in the Light of Business and IT Alignment
The need to reduce a gap between organizational context and technology within enterprise has been recognized and discussed by both researchers and practitioners. In order to solve this problem it is required to capture and analyze both business and IT dimensions of enterprise operation. In this regard, Enterprise Modeling is currently considered as widely used and powerful tool that enables and...
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...
