Diversity and Multiplexing of Opportunistic Shared Relay Channel and the X-Relay Channel

GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
In this paper we study opportunistic communication in two relay channels, the shared relay channel (SRC) and the X-relay channel (XRC). The shared relay channel consists of multiple non-interfering source-destination pairs sharing one relay. The X relay channel is a multi-source multidestination network where each source has a message for each ...

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 ...

Improving diversity of relay channels: Beamforming and relay selection

2008 IEEE 16th Signal Processing, Communication and Applications Conference, 2008
In this paper, the performance of various beamforming and relay selection schemes for fading relay channels, are investigated. Beamforming schemes that maximize the diversity of the system for amplify&forward (AF) and decode&forward (DF) methods, are proposed.

User selective relaying in multiple access relay channels

2012
Network coding has recently received significant attention as an innovative approach to improve the throughput of wireless communication systems. The multiple access relay channel (MARC), in which multiple users communicate with a common destination via a relay, is one of the important network coding applications for wireless cooperative communications.
