Abstract:In this paper, we investigate the Power Allocation (PA) problem for
Cooperative Orthogonal Frequency Division Multiplexing (C-OFDM)
communication system with a relay which Decodes and Forwards (DF)
the data and with Binary Differential Phase Shift Keying (BDPSK)
modulation. We propose the optimal power allocation algorithms to
minimize Average Bit Error Rate (ABER). In the optimal algorithms,
the system firstly allocates power for each sub-carrier pair, and
then allocates power in every sub-carrier pair. In addition, the
performance of optimal scheme with simple sub-carrier pairing
proposed in this paper is better. Simulation results show that
significant performance gains can be achieved by the proposed
algorithms.
