本文解决了多输入多输出（MIMO）中继信道容量上限和下限的优化问题。特别是，我们表明评估割集界限和最大可实现的解码转发率相当于解决凸优化问题，其中我们假设完美的信道状态信息在所有节点都可用。因此，我们的优化边界改进了之前发布的结果，同时可以使用凸规划技术有效地确定它们。
This paper addresses the optimization of upper and lower bounds on the capacity of the multiple-input multiple-output (MIMO) relay channel. In particular, we show that evaluating the cut-set bound and the maximal achievable decode-and-forward rate is equivalent to solving convex optimization problems, where we assume that perfect channel state information is available at all nodes. Our optimized bounds thus improve on previously published results while they can be efficiently determined using convex programming techniques at the same time.
