| 针对车载HF跳频电台的共址干扰问题进行了较为全面和深入的研究。首先对共址平台
和天线耦合度进行了分析，并通过建立有线实验平台和理论模型，深入研究了功率、频率、
误码率等参数之间的相互关系。在此基础上，通过分析HF组网的约束条件，建立了综合共址
干扰、跳频、组网等因素的误码率计算模型。实例分析表明，模型为评估系统性能和配置电
台工作参数提供了理论依据。 |

| Abstract: |
| For the cosite interference(CI) problem of vehicular HF frequency-hoppi
ng(FH) radio, a comprehensive and in-depth research is conducted. Firstly, the
CI platform and antenna coupling are analysed. Through establishing the wired ex
periment platform and theoretical model, the relationships between the power, fr
equen
cy, BER and other parameters are investigated. Based on these studies, through a
nalysing the constraint conditions of HF FH networking, the BER computational mo
del which includes CI, FH, networking and other factors is established. The exam
ple analysis shows that the model is the theoretical basis in evaluating system
performance and arranging parameters of radios. |
| Key words: vehicular FH radio co-site interference coupling BER computation system performance |
