In this paper, the non-selective Decode-and-Forward (DF) scheme proposed in is analyzed using approximate Gaussian density evolution (DE). Based on the DE analysis, performance is shown to be improved by adaptively changing the transmit code at the relay node in response to the channel conditions. Simulation results show that the proposed adaptive scheme improves performance, particularly when the...
This paper investigates proactive relay selection (PRS) in distributed cooperative networks with multiple potential relays and multiple source-destination pairs. A simple PRS scheme is proposed and its outage probability is analyzed. Compared with the reactive relay selection (RRS) scheme proposed in, our PRS scheme has a loss on the outage performance. However, its significance lies in three aspects:...
Cooperative wireless communications offers a new dimension of diversity by emulating transmit antenna diversity to provide reliable communications. In cooperative diversity, single-antenna radios behave as relays between a source and destination, and the performance improvements are due to cooperation of the source and the relay. However, a misbehaving relay can degrade the envisaged performance improvements...
