The use of multiple-antenna nodes in communications is a known technology to increase capacity and improve reliability, especially when compared with single-antenna node networks.
Furthermore, in [7] the Rayleigh performance of a single-relay cooperative scenario with multiple-antenna nodes is investigated, deriving pairwise error probability (PEP) expressions.
In this paper, we extend the idea of distributed space-time coding to wireless relay networks with multiple-antenna nodes and fading channels.
The paper "Diversity analysis of distributed space-time codes in relay networks with multiple transmit/receive antennas" by Y. Jing and B. Hassibi extends the concept of DSTC to wireless relay networks with multiple-antenna nodes and analyzes the pairwise error probability at high SNR.
Our system is built on the idea of distributed space-time coding [3, 9], where multiple nodes cooperate to transmit a signal which approximates the transmission of a single, multiple-antenna node.
To validate the circuit design based on the proposed architecture, the implementation is done on a test bed that includes one central processor with multiple distributed antenna nodes and multiple mobile stations.
COSTBCs, in comparison, achieve the maximum diversity gain with linear decoding complexity (similar to [14 21]) in a multi-hop network with multiple antenna equipped nodes, even though they do not have the single symbol decodable property.
It extends the evaluation of the opportunistic synchronous array method (O-SAM) protocol, which adapts to channel gain variations within a local area or subnet, to general loading conditions and multiple antennas per node.
The multi-antenna access point's transmission is used for information-decoding by a multi-antenna node and for energy-harvesting (EH) by multiple single-antenna nodes.
We propose non-regenerative multi-way relaying where a half-duplex multi-antenna relay station (RS) assists multiple single-antenna nodes to communicate with each other.
In particular, for a three-node multiple antenna SWIPT system, the optimal precoder was designed to achieve information and energy transmission trade-off [1].
