研究了半双工高斯多输入多输出（MIMO）中继信道的割集界（CSB）和解码转发（DF）速率的优化问题。特别是，它表明，评估割集界和最大可实现的DF率是相当于解决凸优化问题，如果完美的信道状态信息（CSI）是在所有节点。因此，我们的工作扩展了全双工中继信道的结果，我们也在这里重新访问，它表明，它是可以有效地确定（一般宽松）的半双工MIMO中继信道的容量的界限。
In this paper, the optimization of the cut-set bound (CSB) and the achievable decode-and-forward (DF) rate for the half-duplex Gaussian multiple-input multiple-output (MIMO) relay channel is considered. In particular, it is shown that evaluating the cut-set bound and the maximal achievable DF rate is equivalent to solving convex optimization problems if perfect channel state information (CSI) is available at all nodes. Our work therefore extends results for the full-duplex relay channel, which we also revisit here, and it demonstrates that it is possible to efficiently determine (generally loose) bounds on the capacity of the half-duplex MIMO relay channel.
