This report presents a practical implementation of a novel two-phase, three-message strategy for half-duplex relaying, which consists of superposition coding and interference-aware cancellation decoding. As opposed to past works, the channel model has a direct link between the source and the destination, through which the source continuously sends information to the destination at a rate close ...

Motivated by the compressive sensing (CS) theory and its close relationship with low-density parity-check code, we propose compressive transmission which utilizes CS as the channel code and directly transmits multi-level CS random projections through amplitude modulation. This article focuses on the compressive cooperation strategies in a relay channel. Four decode-and-forward (DF) strategies, ...

In this paper, the cooperative diversity with superposition modulation, which has been proposed as an instance of “dirty paper coding”, is theoretically analyzed using the outage probability. However, the conventional system with superposition modulation cannot ideally perform dirty paper coding. Thus, we propose to apply constellation rotation technique and iterative processing to the superpos...

The density of radio access points in currently deployed cellular networks increases in order to improve the reuse of available resources and to serve more user terminals at high data rates. This implies higher deployment costs, which demands low-cost and flexible alternatives. However, this ambitious goal cannot be accomplished with conventional cellular systems but requires new technologies s...

Full-duplex (FD) wireless is an attractive communication paradigm with high potential for improving network capacity and reducing delay in wireless networks. Despite significant progress on the physical layer development, the challenges associated with developing medium access control (MAC) protocols for heterogeneous networks composed of both legacy half-duplex (HD) and emerging FD devices hav...

Although extensively investigated, the capacity of the two-hop half-duplex (HD) relay channel is not fully understood. In particular, a capacity expression which can be evaluated straightforwardly is not available and an explicit coding scheme which achieves the capacity is not known either. In this paper, we derive a new expression for the capacity of the two-hop HD relay channel based on a si...

In a transmitter-cooperative network, the source nodes help each other and jointly encode their data, so as to maximize their mutual benefits. In this paper, we focus on a half-duplex four-node network, and study the feasible achievable rates. A transmission scheme, called exchange-and-forward, is proposed. In this scheme, the messages from the two source nodes are first exchanged, and then joi...
