Relaying strategies for the interference relay channel

2012 IEEE 13th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2012
In this paper, the two-user interference relay channel (IRC) is studied. Transmission schemes for this network are compared. Namely, compress-and-forward (CF) and functional decode-and-forward (FDF) are presented. In CF, the relay establishes cooperation with the users by compressing its observation and forwarding it to the receivers. In FDF, the relay

The geometry of the relay channel

2017 IEEE International Symposium on Information Theory (ISIT), 2017
Consider a memoryless relay channel, where the channel from the relay to the destination is an isolated bit pipe of capacity C 0 . Let C(C 0 ) denote the capacity of this channel as a function of C 0 . What is the critical value of C 0 such that C(C 0 ) first equals C(∞)?

Relay Channel With Private Messages

IEEE Transactions on Information Theory, 2007
The relay channel with private messages (RCPM) is a generalized relay channel model where in addition to the traditional communication from source to destination (assisted by relay), the source has a private message for the relay, and the relay has a private message for the destination.

The Multiple-Relay Channel with Estimate-and-Forward Relaying

2007 IEEE International Symposium on Information Theory, 2007
In this paper we consider the multiple-relay channel. For this scenario there are two well known results: the decode-and- forward (DAF) result of [Xie and Kumar, 2005] and the estimate-and forward (EAF) result of [Kramer et al., 2005]. However, the EAF result does not lend itself to numerical evaluation due to the large number of parameters to be ...

Optimal Relay Location for Fading Relay Channels

2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010
In this paper we study the problem of relayenhanced cell (REC) coverage for which relay location is optimized to maximize the achievable REC radius. The problem is investigated for both Rayleigh and Rician relay fading channels, under a pre-determined user's outage probability constraint.

The Gaussian Interference Relay Channel with a Potent Relay

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
We consider the Gaussian interference channel with an intermediate relay. The relay is assumed to have abundant power and is named potent for that reason. A main reason to consider this model is to find good outerbounds for the Gaussian interference relay channel (GIFRC) with finite relay power. By setting the power of the relay constraint to infinity,
