在这封信中，我们评估了中断性能的模拟网络编码（ANC）协议的双向半双工中继系统与非对称业务的要求，在终端。我们推导出一个简单的和广义的瑞利平坦衰落环境中的整个系统中断概率的表达式。我们也推导出最佳的中继位置和功率分配，以尽量减少整个系统的中断。数值和仿真结果突出了各种业务需求下的最佳中继定位和功率分配的效果。
In this letter, we evaluate the outage performance of analog network coding (ANC) protocol for a two-way half-duplex relaying system with asymmetric traffic requirements at end terminals. We derive a simple and generalized expression for overall system outage probability in a Rayleigh flat-fading environment. We also deduce the optimal relay location and power allocation in order to minimize the overall system outage. Numerical and simulation results highlight the effect of optimal relay positioning and power allocation under various traffic requirements.
