摘要 分析研究了GPS宽带干扰抑制的各种空时自适应处理算法,提出了期望信号协方差矩阵的计算方法,该方法使得最大信干噪比方法和最小均方误差方法可以实现。仿真结果表明:和无干扰的GPS接收机相比,基于空时自适应的干扰抑制技术不会引起很大的定位误差。 Adaptive space-time processing algorithm for GPS wideband interference suppression is studied and analyzed in this paper. In order to implement the maximum signal-to-interference-plus-noise ratio method and minimum mean square error method,a calculated formula for eovarianee matrix of desired signal is provided. The simulation results show that interference suppression methods based on the spaee-time adaptive processing can not lead to poor positioning error compared with GPS receiver without interference.
