Cooperative Communication in Wireless Relay Networks

Popis výsledku v původním jazyce

The communication strategies based on the principles of network coding and relaying possess a great potential to increase data throughput in the future wireless mobile networks. Idea of hierarchical data processing was introduced in the Hierarchical Decode and Forward (HDF) strategy. A sophisticated design of modulation/coding for HDF is necessary to avoid detrimental effects of wireless channel parameterization. Extension of the HDF principle to the perspective Ultra-Wide Band (UWB) systems was also found to be non-trivial. A stand-alone research area is represented by the issues related to the cooperative relay/destination processing. In this paper we introduce an example of latency-reducing Compress and Forward (CF) strategy and a systematic designof continuous message representation for Sum-Product Algorithm on Factor Graphs (FG), suitable for an iterative receiver in a general multi-node network.
