一种共址平台装备的射频干扰抑制系统设计方法
A Design Method of Co-platforms Radio Frequency Interference Suppression System
摘要
Abstract
In co-platforms,radio frequency(RF)interference is a key problem to the high sensitivity receiver when the high power transmitter works.In order to suppress the interference,the multi-tap RF self-interference cancellation structure is utilized.By controlling the weight of delay,amplitude and phase,the generated signal's amplitude is equal to the interference signal and the phase is opposite.To achieve the best performance,a method based on optimization algorithm is proposed to obtain the multi-tap's best control weight.Compared with the traditional method,the proposed method shows the merits of high interference suppression ratio,few number of taps and low demand on the digital control circuit.关键词
