本文研究了基于放大转发（AF）的模拟网络编码（ANC）中继选择（RS）协议。我们考虑一个双向网络，由两个不同的终端源和多个继电器，其中每个终端有一个单一的天线，并在一个半双工模式下工作。在该网络中，根据信道条件选择单个最佳中继，以帮助两个端源之间的双向通信。具体来说，我们首先考虑一个RS计划的ANC协议的基础上的最大-最小准则，以尽量减少中断概率。然后，我们推导出一个封闭形式的中断概率。数值结果证实了ANC协议的封闭形式的表达是非常准确的。
We study relay selection (RS) with the analog network coding (ANC), which is an amplify-and-forward (AF)-based protocol in bidirectional relay networks. We consider a bidirectional network consisting of two different end-sources and multiple relays, where each terminal has a single antenna and operates in a half-duplex mode. In this network, a single best relay is selected depending on channel conditions to help bidirectional communication between the two end-sources. Specifically, we first consider an RS scheme for the ANC protocol based on a max-min criterion to minimize the outage probability. Then we derive a closed-form outage probability. Numerical results confirm that the closed-form expression of the ANC protocol is very accurate.
