TD-LTE系统大气波导远端干扰解决方案研究

摘要

大气波导效应使得通信系统间干扰问题变得极为复杂，影响网络质量，降低了无线用户的感知。通过大气波导远端干扰缓解和自适应协调解决远端干扰问题，分干扰缓解、干扰源检测、自适应协调这三步实现干扰监测与缓解。实测结果表明在平均干扰电平升高的情况下，接通率、切换成功率和掉线指标有较明显提升，有助于提升用户感知。%Atmospheric ducting effect extremely complicates the inter-communication system interference problem, inlfuences network quality, and reduces wireless user perception. This innovative solution solved the distal interference problem through the distal end of the ducting and adaptive interference mitigation coordination, it used three steps to achieve interference monitoring mitigation, and they were interference mitigation, the source of interference detection, adaptive monitoring and coordination. Test results show that when the average interference level rise, the connection rate, switching success rate and disconnection index are signiifcantly improved, helping improve user perception.
