在本文中，我们提出了一种新的协作中继网络配置空间复用和波束成形。该系统结构基于两跳放大转发中继协议，具有复杂度低、易于实现的特点。本文推导了系统容量的闭式公式，并在信噪比最大化和容量最大化准则下，与普通协作系统的系统容量和误码率性能进行了比较和分析。数值仿真和链路级仿真结果表明，将波束赋形技术应用于协作中继系统中，可以提高协作中继网络的性能，尤其是在信道独立的情况下。
In this paper, we propose a novel cooperative relay network configuration with spatial multiplexing and beamforming. The proposed system configuration is based on two-hop amplify-forward relay protocol for its low complexity and easy implementation. In our work, we deduce the closed-form formulas of the system capacity, and under SNR maximizing and capacity maximizing criterions, we compare and analyze the system capacity and BER performances with that of common cooperative system. Our numerical and link level simulations show that applying the beamforming into the cooperative relay system can brings to common cooperative relay network performance gain, especially when the channel is independent.
