摘要 在码分多址(CDMA)的多无人机扩频测控链路中,多址干扰(MAI)是多目标系统需考虑的重要因素。在此类系统中,针对抗多址干扰的要求,设计具有相应互相关性能的扩频码是首要任务。从多无人机对抗多址能力的需求入手,分析了码速率、用户个数以及码的互相关性能对抗多址干扰能力的影响,得出了Kasami码型互相关性较好、序列部分相关会降低互相关性能的结论。仿真结果验证了理论分析的正确性。 In Code Division Multiple Access(CDMA) multi-UAV TT&C spread spectrum link,Multiple Access Interference(MAI) is an important factor to be considered in multi-target system in which the first task is to design spread spectrum code with cross correlation according to the anti-MAI requirement.Starting with the requirement of UAV for anti-MAI capability,this paper analyzes the effect of such factor as spread spectrum rate,number of users, and cross correlation on anti-MAI performance,draws the conclusion that the Kasami code has good cross correlation and the sequence partial correlation can reduce the cross correlation performance.Simulation result verifies the theoretical analysis.
