Abstract:
In this paper, we propose joint cooperativetransmit/
receive frequency-domain equalization(cooperative-Tx/Rx
FDE) with incremental relaying (IR) for broadband single-carrier
(SC) transmission under the total and individual transmit power
constraint at a source node (S) and a relay node (R). We derive
the optimum cooperative-Tx/RxFDEweights to minimize the mean
square error (MSE) after packet combining at a destination node
(D). We show that the optimum cooperative-Tx FDE weights
allocate the transmit power in the minimum MSE (MMSE) sense
in the frequency domain and in the maximal ratio transmission
(MRT) sense in the spatial domain. To relax the condition that
the complete channel state information (CSI) needs to be shared
among all nodes, selection-based suboptimum cooperative-Tx FDE
weights are derived. Computer simulation verifies the effectiveness
of the proposed schemes and shows that the 5%-outage throughput
of the system can be increased by around 30% over the conventional
IR with only Rx FDE.
