摘要：
Optimal relay precoding design is studied for spectrum sharing non-regenerative multi-hop MIMO cognitive relay systems. By exploiting multiple antennas at all the nodes, the optimal structures of all the relay precoding matrices are derived, aiming to maximise the system capacity subject to the transmit power constraints at the relays and the interference power constraints at the primary user. The effectiveness of the proposed precoding is validated by simulation results.
