In this paper, we analyze the performance of vehicle-to-vehicle (V2V) communication system, which employs full-duplex (FD) and energy harvesting (EH) techniques at source and relay nodes from power beacon (PB) through radio frequency. Unlike previous systemswhere all nodes located at fixed locations, we investigate the case that three nodes (source, relay,and destination) are moving vehicles. Therefore, the channels between them follow double (cascade) Rayleigh fading distributions. Furthermore, the source and relay nodes can harvest the energy from PB for data transmission when they move on the road. We derive the exact expressions of the outage probability (OP) and symbol error probability (SEP) of the proposed system and then intensively study the impacts of various parameters such as the number transmission antennas of PB, the time duration for EH, the distances between nodes, and the residual self-interference (RSI) at the FD relay node on the system performance. Monte-Carlo simulations validate all theory analysis. Numerical results show that system performance is strongly impacted by the number of transmission antennas of the power beacon, the EH duration, the RSI, and the distances between nodes. Moreover, for a given transmission of power beacon and the SIC capability of the FD relay node, there exist optimal EH duration and optimal distance from the source to relay, which provide the best system performance.

在本文中，我们分析了车对车（V2V）通信系统的性能，该系统在从电源信标（PB）到射频的源节点和中继节点处采用全双工（FD）和能量收集（EH）技术。与以前的系统中所有节点都位于固定位置的系统不同，我们调查了三个节点（源，中继和目的地）在移动车辆的情况。因此，它们之间的信道遵循双（级联）瑞利衰落分布。此外，当源节点和中继节点在道路上移动时，它们可以从PB收集能量以进行数据传输。我们推导了所提出系统的中断概率（OP）和符号错误概率（SEP）的精确表达式，然后深入研究了各种参数的影响，例如PB的数量传输天线，EH的持续时间，节点之间的距离以及FD中继节点上的剩余自干扰（RSI）对系统性能的影响。蒙特卡洛模拟验证了所有理论分析。数值结果表明，系统性能受到信标发射天线数量，EH持续时间，RSI和节点之间距离的强烈影响。而且，对于给定的功率信标传输和FD中继节点的SIC能力，存在最佳的EH持续时间和从源到中继的最佳距离，这提供了最佳的系统性能。数值结果表明，系统性能受到信标发射天线数量，EH持续时间，RSI和节点之间距离的强烈影响。此外，对于给定的功率信标传输和FD中继节点的SIC能力，存在最佳的EH持续时间和从源到中继的最佳距离，这提供了最佳的系统性能。数值结果表明，系统性能受到信标发射天线数量，EH持续时间，RSI和节点之间距离的强烈影响。而且，对于给定的功率信标传输和FD中继节点的SIC能力，存在最佳的EH持续时间和从源到中继的最佳距离，这提供了最佳的系统性能。
