In this paper a diagonal cyclotomic space-time coding (DCSTC) transmission scheme for wireless cooperative relay networks is proposed. We consider the full-duplex cooperation which is more spectrally efficient than the half-duplex cooperation. By the combination of multidimensional complex constellation symbols rotation and Hadamard transform, the proposed scheme is capable of achieving full cooperative diversity. A large number of relay nodes may be employed in the cooperative system. The pairwise error probability (PEP) and the coding gain with the optimal total transmit power allocation is analyzed. It is not required with decoding and demodulation at the relay node, resulting in lower complexity. Besides, there is no delay with regards to re-transmission from delay nodes to destinations. At the destination node, the DCSTC structure can be exploited on the received signals, which is easily decoded by the fast sphere decoder. Simulation results show that the proposed scheme achieves full cooperative diversity and largely improves the network performance. |
