Joint Resource Allocation and Antenna Selection In the Uplink of OFDMA Networks
Ata Khalili, Soroush Akhlaghi, Sayed Ali Khodam Hoseini
The problem of joint sub-channel, power control and antenna selection in the uplink of OFDMA networks is investigated. The corresponding optimization problem is a non convex mixed…
Asymptotic Close To Optimal Joint Resource Allocation and Power Control in the Uplink of Two-cell Networks
Ata Khalili, Soroush Akhlaghi, Meysam Mirzaee
In this paper, we investigate joint resource allocation and power control mechanisms for two-cell networks, where each cell has some sub-channels which should be allocated to some…
Maximizing the minimum achievable secrecy rate of two-way relay networks using the null space beamforming method
Erfan khordad, Soroush Akhlaghi, Meysam Mirzaee
This paper concerns maximizing the minimum achievable secrecy rate of a two-way relay network in the presence of an eavesdropper, in which two nodes aim to exchange messages in two…
Minimizing The Expected Distortion Using Multi-layer Coding Approach In Two-Hop Networks
Sayed Ali Khodam Hoseini, Soroush Akhlaghi, Mina Baghani
This work concerns minimizing the achievable distortion of a Gaussian source over a two-hop block fading channel under mean square-error criterion. It is assumed that there is not…
Secrecy Capacity of Two-Hop Relay Assisted Wiretap Channels
Meysam Mirzaee, Soroush Akhlaghi
Incorporating the physical layer characteristics to secure communications has received considerable attention in recent years. Moreover, cooperation with some nodes of network can…
A Non-MDS Erasure Code Scheme For Storage Applications
Abbas Kiani, Soroush Akhlaghi
This paper investigates the use of redundancy and self repairing against node failures in distributed storage systems, using various strategies. In replication method, access to on…
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.…
