A Fixed Precoding Approach to Achieve the Degrees of Freedom in X channel
Soroush Akhlaghi, Mohammad Ali Maddah-Ali
This paper aims to provide a fixed precoding scheme to achieve the Degrees of Freedom DoF of the generalized ergodic X channel. This is achieved through using the notion of ergodic…
Cost-Bandwidth Tradeoff In Distributed Storage Systems
Soroush Akhlaghi, Abbas Kiani, Mohammad Reza Ghanavati
Distributed storage systems are mainly justified due to the limited amount of storage capacity and improving the reliability through distributing data over multiple storage nodes.…
