A two-hop amplify-and-forward scheme for extended orthogonal space time coding in cooperative networks
conference contribution
posted on 2009-10-01, 08:50 authored by Nasr E.M. Eltayeb, Shakiru K. Kassim, Jonathon ChambersWe investigate and propose a new amplify-and-
forward cooperative relay networks scheme in
which a full-rate and full-diversity extended-
orthogonal space-time block coding (EOSTBC)
scheme is used. Utilizing a feedback channel,
a simple phase rotation is applied at the relay
nodes to extract full diversity and array gain. A
feedback quantization approach which reduces
the overhead in the feedback channel for prac-
tical systems is also proposed. The performance
of the proposed scheme, with and without opti-
mum power allocation strategy, is investigated.
Average bit error rate simulations confirm the
utility of the scheme. The results also confirm
the improvement in bit error rate (BER) perfor-
mance over quasi-orthogonal space time block
codes (QOSTBC).
