摘要：

In this paper, the capacity of MIMO relay channel with decode and forward (DF) scheme is investigated, where each node within the system quipped with multiple antennas and located in an environment with distance-dependent path loss. In order to achieve the maximum capacity of the system, the optimal power allocation (OPA) among the nodes and the transmit antennas is analyzed under the assumption that relay node knows all channels instantaneous state information (CSI), and an implement algorithm of the OPA is derived. Numerical results demonstrate that adopting the proposed power allocation algorithm, the capacity of MIMO relay channel with DF relay scheme can be significantly improved.
