Extended orthogonal space time block codes in wireless relay networks
conference contribution
posted on 2010-01-22, 15:52 authored by Faisal T. Alotaibi, Jonathon ChambersIn this paper we propose complex extended orthogonal space-time
block codes (EO-STBCs) with feedback for wireless relay networks
with the assumption of quasi-static flat fading channels. Full rate in
each stage and full cooperative diversity for distributed EO-STBCs
(D-EO-STBCs) are achieved by providing channel state information
(CSI) at certain relay nodes. Two closed-loop schemes are proposed
which make use of limited feedback from the destination node to
a particular number of relay nodes, not exceeding half of the total
number of such relay nodes. In our simulations, we use four relay
nodes. Simulation results show that these two closed-loop D-EOSTBCs
achieve full cooperative diversity in addition to array gain
with linear processing. In particular, the proposed D-EO-STBCs designs
preserve low decoding complexity and save both transmission
power and total transmit time between source and destination.
