Abstract
Due to the lack of effective methods for broadband interference suppression in aerospace TT&C system, the receiving structure of the directional antenna and the omni-directional antenna is provided.Non-cooperative signal is cancelled at RF domain, so as to ensure the accurate reception of the cooperative signal.Two syntactic models of the single tap and the multi-tap are discussed separately.Theoretical derivation is proceeded with minimizing the residual non-cooperative signal power as criterion by using the interference cancellation algorithm.It is suggested that the vector modulator be used to adjust the amplitude and phase in the multi-tap structure.The simulation result shows that, for the single tap structure, when the delay line error is 2%, the best interference cancellation capability reaches 45 dB in the 2.6 GHz band, for the关键词
