摘要: 该文针对有限区域的同时同频全双工(CCFD)跳频自组网络，通信节点位置不等价，受非对称互干扰和自干扰影响的场景，开展有限区域全双工跳频自组网的通信性能分析。以网络频带利用率为性能指标，推导出节点位置分布条件下的网络频带利用率闭合表达式，并提出一种降低网络互干扰的节点位置优化分布方法。理论和仿真结果表明，有限区域全双工跳频自组网的性能与频点个数、通信距离、节点个数强相关，且全双工自组网络的性能与半双工网络相比，其占优区域受节点个数约束。Abstract: For Co-frequency and Co-time Full Duplex (CCFD) frequency hopping ad hoc network in finite area, communication performance analysis is proposed considering the scenario of self-interference and asymmetric mutual interference caused by unequal position of communication nodes. Taking the network band utilization as the performance index, the closed expression of network band utilization under the condition of node location distribution is derived, and a node location optimization distribution method reducing network mutual interference is proposed. Simulation results show that the performance of full duplex frequency hopping ad hoc network in finite area is strongly related to the number of frequency points, communication distance and the number of nodes. Besides, whether the performance of full duplex ad hoc network is better than half duplex network depends on the number of nodes.
