Relay-aided Interference Alignment in Wireless Networks

Resource management in wireless networks is one of the key factors in maximizing the overall throughput. Contrary to popular belief, dividing the resources in a dense network does not yield the best results. A method that has been developed recently shares the spectrum amongst all the users in such a way that each node can potentially utilize about half of all the available resources. This new ...

Degrees of Freedom of Cache-Aided Wireless Interference Networks

We study the role of caches in wireless interference networks. We focus on content caching and delivery across a Gaussian interference network, where both transmitters and receivers are equipped with caches. We provide a constant-factor approximation of the system’s degrees of freedom (DoF), for arbitrary number of transmitters, number of receivers, content library size, receiver cache size, an...

Cache-enabled Wireless Networks with Opportunistic Interference Alignment

Both caching and interference alignment (IA) are promising techniques for future wireless networks. Nevertheless, most of existing works on cache-enabled IA wireless networks assume that the channel is invariant, which is unrealistic considering the time-varying nature of practical wireless environments. In this paper, we consider realistic time-varying channels. Specifically, the channel is fo...

Channel Aided Interference Alignment

Interference alignment (IA) is a transmission strategy that attempts to exploit all degrees of freedom available at the transmitter or at the receiver in a multiuser channel. This paper proposes a new scheme named channel aided interference alignment. It makes use of the channel structure beside the linear interference alignment schemes to achieve the optimum degrees of freedom in a K user inte...

Interference Alignment and Power Control for Wireless Interference Networks

This thesis deals with the design of efficient transmission schemes for wireless interference networks, when certain channel state information (CSI) is available at the terminals. In wireless interference networks multiple source-destination pairs share the same transmission medium for the communications. The signal reception at each destination is affected by the interference from unintended s...
