Buffer-Aided Link Selection for Incremental Relaying Systems

Darabi, Mostafa; Maham, Behrouz; Zhang, Yan (2014 IEEE Symposium on Computers and Communications (ISCC), 2014)

In this paper, we consider a three-node wireless network comprising of a source and two users. Both users need to decode the transmitted data correctly. User 1 has better position to the source than user 2 most of time ...
Orthogonal Code Design for MIMO Amplify-and-Forward Cooperative Networks

Maham, Behrouz; Hjørungnes, Are (2010 IEEE Information Theory Workshop on Information Theory (ITW 2010, Cairo), 2010)

This paper is on the design of practical distributed space-time codes for wireless relay networks with multiple antennas terminals. The amplify-and-forward scheme is used in a way that each relay transmits a scaled version ...
Outage Probability Analysis of Multi-Relay Delay-Limited Hybrid-ARQ Channels

Maham, Behrouz; Hjorungnes, Are; Debbah, Merouane (2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010)

We consider a wireless relay network with with hybrid-automatic retransmission request (HARQ) and Rayleigh fading channels. In this paper, we analyze the outage probability of the multi-relay delay-limited HARQ system with ...
Relay X Channels without Channel State Information at the Transmit Sides: Degrees of Freedom

Zebardast, Hamideh; Tajer, Ali; Maham, Behrouz; Rezaee, Mohsen (2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015)

This paper focuses on the two-user relay-assisted X channel with no channel state information (CSI) available at the transmitter side. Two relaying modes, namely half-duplex decode-and-forward (DF) and cognitive relays, ...
