摘要
本文用系统的调制－解调综合特性、幅相频率特性、乘积解调正交性，分析了多副载波调相传输系统输出的组合干扰，并推导出了组合干扰的表达式，给出了实验结果．
On the basis of modulation-demodulation combined characteristic of system,amplitude-phase frequency characteristics and phase orthogonality of demodulator, the combinationinterference of PM system of multi-subcarrier modulation is analyzed,and the formulas of combination interference are deriverd. The experiment result is given.
