摘要 提出了一个基于高阶瞬态矩迭代的多项式相位干扰的抑制技术。针对振幅恒定和多项式相位特征的干扰信号,运用高阶瞬态矩和迭代法精确综合出相应干扰信号;然后在时域将其从接收信号中减去,以有效地抑制宽带非平稳干扰。性能仿真结果表明,该方法不仅提高了干扰参数估计的精度,降低了计算的复杂度,而且提高了系统处理的实时性和有效地抑制了多项式相位干扰,获得比较好的误码率性能改善。 This paper presents a suppression method for the interference characterized by constant amplitude and ploynomial phase signal（PPS） based on high-order instantaneous moment iterative approach in direct-sequence spread spectrum communication.The phase parameters of ploynomial phase interference are accurately estimated based on high-order instantaneous moment and iterative approach,and the interference amplitudes is estimated by least-square algorithm,then the interference from received signals is synthesized by estimated parameters.The interference contribution can be removed by subtracting synthesized interference from received signals in time domain.Simulation results show that the performance of interference suppression is greatly improved.
