摘要
在分析互扰问题形成机理的基础上,重点测试了杂散信号、谐波信号以及互调干扰信号对通信装备的影响。测试与分析结果表明无论是模拟通信还是数字通信,三阶互调信号有时可以完全压制该信号频率上的正常通信,同时互调信号频率上能否解调出另外两个频率上的信息取决于通信装备的调制解调方式。
The formation mechanism of the mutual interference problem is analyzed, and the influence of the stray signal, harmonic signal and intermodulation signal for communication equipment is also analyzed by testing in the paper. Test and analysis results show that third-order intermodulation signal can sometimes completely suppress the normal communication both analog communication and digital communication, and the two additional information can be demodulated on the intermodulation signal frequency depends on the modulation and demodulation of communication equipment.
