Efficient embedded signaling scheme for nodes identification using block coding with blind phase estimation in relay systems

In this paper, we propose a nodes identification scheme based on embedded signaling for relay systems where a data sequence transmitted by a source node is forwarded by a selected relay node before reaching the destination node. In the proposed identification scheme, source and relay nodes incorporate precoding sequences, based on codewords generated from block codes, into the data sequence. A soft decoding at the destination node allows it to efficiently recover in one step the identities of transmitting source and relay nodes of received packets. The proposed scheme is an alternative to classical explicit identification scheme based on exchanging signaling information before the data exchange and including identities in the data sequences. We also propose a blind estimation technique allowing the destination to estimate the phase of the channel. We consider the Opportunistic Relay Selection (ORS) and the Partial Relay Selection (PRS) to select relay nodes. Numerical results confirm the performance of the proposed identification scheme.
