摘要:
为优化多通信设备系统间的电磁兼容性，提出同频干扰抑制和乱真响应抑制两个层级相分离的层次化优化方法。同频干扰抑制采用多目标遗传算法，以设备安装位置为决策变量，调整设备安装位置和天线方向性来降低干扰影响；在设备布局优化的基础上分析进一步降低同频干扰和潜在乱真响应影响的技术方法，提出针对性的电磁兼容指标优化方案。通过层次化的预测和优化，实现了对通信系统总体电磁兼容性的量化控制，使得电磁兼容指标变动方案与系统总体电磁兼容性优化结果的内在关联更明晰。
To separate co-channel interference inhibition and spurious response inhibition， a hierarchical method is proposed in this paper to optimize the inter-system compatibility of the communication equipment. The multi-objective genetic algorithm is used to restrain co-channel interference， in which the equipment installation locations serve as decisive variables so that the effects of interference reduction mainly depend on adjusting locations of equipment and the antenna directivity. Based on the equipment location optimization， a set of optimization proposals related to specific electromagnetic compatibility indicators is put forward to further suppress potential spurious response and residual co-channel interference. With the presented hierarchical prediction and optimizing， the overall electromagnetic compatibility of the communication equipment has been significantly improved.
