One of the main drawbacks of cooperative communication systems with half-duplex relaying is inefficient use of spectrum. Incremental relaying is an effective technique that overcomes this limitation. In this study, for a single-relay regenerative system, the authors propose a spectrally-efficient incremental relaying scheme that eliminates redundant relay transmissions such that the error propa...

We investigate the effect of imperfect feedback on the ǫ-outage capacity of incremental relaying in the low signal-to-noise ratio (SNR) regime. We show that imperfect feedback leads to a rescaling of the pre-log factor (comparable to the multiplexing gain for networks operating in the high SNR regime) and thus reduces the ǫ-outage capacity considerably. Moreover, we investigate the effect of di...

In this paper we focus our attention in the main two methods of Cooperative Communications: Decode and Forward, and Amplify and Forward, and how they can be used in a new concept of Cooperative Satellite Communications. We present an analysis of both in terms of Symbol Error Rate and Power Allocation and analyze which would be more efficient when relaying information from the satellite to a mob...

In wireless sensor networks, the traditional multi-relay incremental cooperative relaying (MIR) scheme could improve the system throughput over the fading channel enormously by exploiting multiple relay nodes to retransmit the copy of the source packet to the destination in turn, but increase the energy consumption and transmission delay. In order to mitigating the energy consumption and transm...
