研究了极化轨道角动量复用系统在考虑极化干扰影响下的系统容量。以偶极子天线为实际辐射方向图，通过分析其他模式的交叉极化干扰、某一模式的交叉极化干扰和不同模式的共极化干扰对接收模式信号的影响，明确了接收模式信号的组成。在干扰分析的基础上，通过与各向同性天线情况的比较，采用链路距离和载波频率参数，精确地评估了系统容量。数值结果表明，交叉极化干扰从其他模式上升，在定期模式间隔，提出了一个显着的影响系统容量，特别是对于相对较短的链路距离或低载波频率。
This paper investigates the system capacity of polarized orbital angular momentum (OAM) multiplexing considering the impact of polarization interference. Dipole antenna is considered as the practical radiation pattern and the composition of the received mode signal is clarified by analyzing the effect of cross-polarization interference from other modes, as well as both cross-polarization interference in a certain mode and co-polarization interference from different modes. Based on the interference analysis, system capacity is precisely evaluated by comparison with the isotropic antenna case, employing a link distance and carrier frequency parameter. The numerical results show that cross-polarization interference from other modes rises at the regular mode interval, presenting a significant impact on system capacity, particularly for relatively short link distances or low carrier frequencies.
