Cooperative communication has been receiving significant attention in recent years because of the great potential for performance improvement. In this paper, we will consider the joint design of transmit and cooperative beamforming vectors in cooperative systems with a multi-antenna source and multiple single-antenna relays. The cooperative beamforming, performed by distributed relay nodes, is different...
A pilot-aided scheme for the parameter estimation in Paired Carrier Multiple Access (PCMA) satellite communication systems is proposed in this paper. Recently, the asymmetric application mode of PCMA, which is more efficient and pragmatic than the symmetric mode, has been studied with great interest. In our research, carefully selected pilot sequences have been inserted into the frame in an attempt...
