摘要：
A new algorithm is proposed in this paper to solve the problem of multisource distance measurement equipment (DME) pulse interference suppression for global positioning system (GPS) L5 signal. The problem can be treated as DME signal estimation, and then can be taken as a problem of optimization. Based on nonlinear least squares (NLS) criterion, using WRELAX iteration method, the optimization problem can be solved to estimate the multisource DME signal. Once DME pulse interference signal is estimated, then it can be reconstructed, and finally can be eliminated and suppressed. Compared with traditional method, the proposed method can reserve more useful GPS satellite data. The performance of proposed method is verified by numerical simulations.
