高移动无线通信干扰的物理层应对思考

Physical Layer Consideration for the Interference in High Mobility Wireless Communications

从干扰避让、干扰抑制、干扰协调3个层次,针对高移动通信不同的干扰场景、干扰形态和干扰特征,提出混叠信号分离的机理、指导原则、分离方法和评估方法的物理层思考。认为必须在不同场景、网络结构和用户行为模式下,建立有效的干扰模型来分析和研究宽带无线通信网络的信息容量,探讨网络自由度对系统性能的影响,发展新的理论和方法应对干扰。

This article proposes the mechanism, principle, methodology and evaluation method of signal separation for different interference scenarios, different interference form and different interference characteristics in high mobility communications, from the three folds of interference avoidance, interference suppression and interference coordination. It is necessary to formulate effective interference model and study the capacity of wideband wireless communication networks in different communication scenarios, different network structures, and for different user behaviors, investigate the effect of network degree of freedom to system performance, and develop new theory and methodology to handle interference.
