【摘要】：针对基于设备到设备(D2D)的汽车间通信复用蜂窝资源带来的干扰问题,考虑在满足车辆用户(V-UEs)的通信要求下,通过一个启发式算法最大化蜂窝用户(C-UEs)总的吞吐量.首先通过图着色原理将没有干扰的车辆分在同一簇;其次根据分簇结果,利用改进的匈牙利指派算法为V-UEs分配信道;最后通过调整功率最大化C-UEs总的吞吐量.仿真结果表明,此算法能够很好地解决车通信(V2X)的同层干扰和跨层干扰问题,在保证V-UEs通信可靠性的前提下,提高了频谱利用率.
[Abstract]:In view of the interference caused by the communication multiplexing cellular resources between vehicles based on device to device (D2D), this paper considers that under the condition of satisfying the communication requirements of vehicle users (V-UEs), A heuristic algorithm is used to maximize the total throughput of cellular users (C-UEs). First, the vehicles without interference are divided into the same cluster by graph coloring principle; secondly, according to the clustering result, the improved Hungarian assignment algorithm is used to allocate the channel for V-UEs; finally, the power is adjusted to maximize the total throughput of C-UEs. The simulation results show that the algorithm can solve the same layer interference and cross layer interference problem of vehicle communication (V2X), and improve the spectrum efficiency under the premise of guaranteeing the reliability of V-UEs communication.
