In the past decade, relay-assisted communications have been the center focus of intensive research studies. Numerous relying strategies, including amplify-and-forward, decode-and-forward, estimate-and-forward, have been proposed in the context of one-way or two-way relay-networks with the aim to enable communications between one or more pairs of source-destination or to enable information exchange between one or more pairs of transceivers. It turns out that the relay channel belongs to a larger class of channels, namely active channels, where the channel behavior can be adjusted, for optimal performance, somewhere between the two ends of the channel. Such channel adjustability does not exist in traditional channel models (which they are herein referred to as passive channels). Indeed in traditional models of wireless channels, the end-to-end channel is often given and there is no control on the channel behavior. To compensate the channel, one has to either resort to precoding at the transmitter and/or equalize the channel at the receiver.

在过去的十年中，中继辅助通信一直是密集的研究重点。已经在单向或双向中继网络的上下文中提出了许多依赖策略，包括放大转发、解码转发、估计转发，其目的是实现一对或多对源-目的地之间的通信或实现一对或多对收发器之间的信息交换。事实证明，中继信道属于更大类别的信道，即活动信道，其中可以在信道两端之间的某处调整信道行为以获得最佳性能。这样的信道可调节性在传统信道模型（它们在本文中被称为被动信道）中不存在。实际上，在传统的无线信道模型中，端到端信道通常是给定的，并且对信道行为没有控制。为了补偿信道，必须在发射机处采取预编码和/或在接收机处均衡信道。
