A temporal LMS DPI Suppression Algorithm for CDMA-based Passive Detection System

摘要：

One of the major problems in CDMA based passive detection system is how to suppress the strong direct path interference (DPI) effectively. According to the features of the CDMA downlink signal and the DPI suppression requirement, a least mean squares methods (LMS) filtering algorithm based on the time domain is proposed. Theory analysis and simulation results show that at least 30 dB suppression gains can be achieved by using the LMS algorithm.
