We study the problem of joint information and energy transfer in a binary two-hop channel with an energy harvesting relay. We consider a finite battery size at the relay and energy loss in transmitting energy. In other words, to be able to send an energy-contained symbol, the relay must receive multiple energy-contained symbols. Thus, we face a kind of channel with memory. We model the energy saved in the battery as the channel state with the challenge that the receiver does not know the channel state. We propose two different achievable schemes, the first one is based on state-dependent superposition coding and the second one is based on the equivalent timing channel approach. Both of our schemes are based on block Markov coding and backward decoding techniques. Due to these two approaches, we find achievable rates with a single-letter expression for the model.
翻译：我们研究在二进制的两速频道中用能源回收中继器联合信息和能源传输的问题。 我们考虑继电器的有限电池大小和传输能源的能量损失。 换句话说, 要能够发送一个能源装配符号, 中继器必须获得多个能源装配符号。 因此, 我们面对着一种有记忆的频道。 我们将电池中节省的能量作为接收器不熟悉频道状态的挑战。 我们提出了两种不同的可实现计划, 一种是依靠国家的超位编码, 另一种是相同的时间频道方法。 我们的两种计划都基于马尔科夫区编码和后向解码技术。 由于这两种方法, 我们找到了可以实现的频率, 并用单字母表达的模式。
