本文提出了一种用于协作中继网络的自适应空时接收器。使用协作放大转发中继节点，可以增加多输入多输出（MIMO）信道的等级。所提出的接收器基于联合自适应迭代检测和解码算法，自适应地消除同信道干扰并消除多址干扰。自适应接收器采用最小均方（LMS）算法。仿真结果表明，与传统MIMO方案相比，该方案取得了更好的误码率（BER）性能。
In this paper, an adaptive space-time receiver for cooperative relay networks is proposed. Using cooperative amplify-and-forward relay nodes, it is possible to increasing the rank of the multiple-input multiple-output (MIMO) channel. The proposed receiver is based on a joint adaptive iterative detection and decoding algorithm, adaptively cancels co-channel interference and eliminates the multiple access interference. The least mean square (LMS) algorithm is used for the adaptive receiver. Simulation results show that the proposed scheme achieves better bit error rate (BER) performance compared with the traditional MIMO scheme.
