| 摘 要： | 文章提出了一种双中继协同的新型传输方案。采用时分方式,将车间通信网络中两个邻近的中继车辆通过无线协同通道信息交互后形成了一对虚拟天线阵。该方案降低了接收机硬件实现复杂度和对准确的同步要求,便于多个单天线中继车辆间共享天线从而实现协同分集。计算机仿真表明,双中继协同提高了系统处于准静态和时变瑞利衰落中继信道下的抗衰落性能,并能有效地抑制中继差错传播,从而获得较高的分集增益。

| Abstract: | A novel collaborative strategy employing two relays is developed for the multihop Inter-Vehicle Communication(IVC) networks,which has great complexity degradation.Considering TDMA scheme,two nearbour vehicles are conjoined by an interaction radio link to create a Virtual Antenna Array(VAA).Then the collaborative two-relay is integrated into the networks mentioned above,which enables a single-antenna terminal to share its antenna with other terminals easily,and avoids the synchronization requirements in distributed space-time coding systems.Furthermore,except the low complexity in hardware implementation,the proposed method also can enhance the performance of the IVC systems over both the quasi-static fading channel and time varying Rayleigh fading relay channel,which is verified through the Monte-Carlo simulations. |
