本文首先建立一个具有能量收集中继的双跳车联网系统模型,然后描述了功率分流和时间切换技术的工作原理。接着取信噪比作为系统中断的参考指标,分别计算了系统的中断概率和吞吐量。最后在数值模拟中,分析了各个参数对系统性能的影响,并对两种能量收集方案进行比较。 In this paper, vehicle network system model with energy harvesting relay is set up, and then the principle of power splitting and time switching is described. Next the signal to noise ratio is used as the index of the outage, and the outage probability and throughput are calculated respectively. Finally, the effects of each parameter on the system performance are analyzed, and the two energy collection schemes are compared in the numerical results.
