The Approximate Capacity Region of the Gaussian Z-Interference Channel with Conferencing Encoders
Hossein Bagheri, Abolfazl S. Motahari, Amir K. Khandani
A two-user Gaussian Z-Interference Channel (GZIC) is considered, in which encoders are connected through noiseless links with finite capacities. In this setting, prior to each tran…
On the Secure Degrees-of-Freedom of the Multiple-Access-Channel
Ghadamali Bagherikaram, Abolfazl S. Motahari, Amir K. Khandani
A -user secure Gaussian Multiple-Access-Channel (MAC) with an external eavesdropper is considered in this paper. An achievable rate region is established for the secure discrete…
Real Interference Alignment
Abolfazl Seyed Motahari, Shahab Oveis-Gharan, Mohammad-Ali Maddah-Ali +1
In this paper, we show that the total Degrees-Of-Freedoms (DOF) of the -user Gaussian Interference Channel (GIC) can be achieved by incorporating a new alignment technique known…
On the Secure DoF of the Single-Antenna MAC
Ghadamali Bagherikaram, Abolfazl S. Motahari, Amir K. Khandani
A new achievability rate region for the secure discrete memoryless Multiple-Access-Channel (MAC) is presented. Thereafter, a novel secure coding scheme is proposed to achieve a pos…
