In two-way relaying, two sources exchange information via a relay. In the generalized two-way relay, private information is also sent by each source to the relay, which may be used for overhead data, such as for channel state information. We consider the generalized two-way relay in a multi-carrier system over the wireless channel. Our problem is to maximize the rate that the sources exchange information,...
We consider two sources that cooperatively send their messages to a destination over Rayleigh-fading channels. Assuming a decode-and-forward scheme, we obtain conditions to achieve the maximum diversity order for a general class of modulation schemes. This class includes the BPSK modulation where the mutual information is bounded, and Gaussian signaling where the mutual information is unbounded. With...
We introduce the multiple access relay channel with generalized feedback (MARC-GF), which is more general than the known MARC (without feedback) and MAC-GF (without relay). In the MARC-GF, two sources, assisted by a common relay, send independent messages to a destination. The sources and relay each receives some feedback that may facilitate this communication. We propose and analyze a decode-and-forward...
Previously proposed technique called joint cooperative diversity and scheduling (JCDS) has been shown to increase aggregate throughput of multiuser OFDMA relay networks significantly while being able to maintain per-link throughput when the number of relays is high enough. This paper proposes a new technique so-called joint cooperative diversity and proportional fair scheduling (JCPFS) for the multiuser...
