A Nonlinear Approach to Interference Alignment
Peyman Razaghi, Giuseppe Caire
Cadambe and Jafar (CJ) alignment strategy for the K-user scalar frequency-selective fading Gaussian channel, with encoding over blocks of 2n+1 random channel coefficients (subcarri…
Two Birds and One Stone: Gaussian Interference Channel with a Shared Out-of-Band Relay of Limited Rate
Peyman Razaghi, Song Nam Hong. Lei Zhou, Wei Yu +1
The two-user Gaussian interference channel with a shared out-of-band relay is considered. The relay observes a linear combination of the source signals and broadcasts a common mess…
On Achievability of Gaussian Interference Channel Capacity to within One Bit
Peyman Razaghi, Giuseppe Caire
In the earlier version of this paper, it was wrongly claimed that time-sharing is required to achieve the capacity region of the Gaussian interference channel to within one bit, es…
Relay Strategies Based on Cross-Determinism for the Broadcast Relay Channel
Peyman Razaghi, Giuseppe Caire
We consider a two-user Gaussian multiple-input multiple-output (MIMO) broadcast channel with a common multiple-antenna relay, and a shared digital (noiseless) link between the rela…
Coarse Network Coding: A Simple Relay Strategy to Resolve Interference
Peyman Razaghi, Giuseppe Caire
Reminiscent of the parity function in network coding for the butterfly network, it is shown that forwarding an even/odd indicator bit for a scalar quantization of a relay observati…
Parity Forwarding for Multiple-Relay Networks
P. Razaghi, W. Yu
This paper proposes a relaying strategy for the multiple-relay network in which each relay decodes a selection of transmitted messages by other transmitting terminals, and forwards…
