An Efficient Method for GPS Multipath Mitigation Using the Teager-Kaiser-Operator-Based MEDLL
An efficient method for GPS multipath mitigation is proposed. The motivation for this proposed method is to integrate the Teager-Kaiser Operator (TKO) with the Multipath Estimating Delay Lock Loop (MEDLL) module to mitigate the GPS multipath efficiently. The general implementation process of the proposed method is that we first utilize the TKO to operate on the received signal’s Auto-Correlatio...
متن کاملThe Case for Narrowband Receivers
Most high performance GPS receivers today are wideband. In most cases, they require the wider precorrelation bandwidth for enhanced multipath mitigation capability. Wideband receivers, however, are still significantly more susceptible to electromagnetic interference. In addition, they are more likely to produce unacceptably large pseudorange errors in the presence of satellite signal anomalies,...
متن کاملSession 3A3 Sensor Array Signal Processing Survey on Interference Mitigation via Adaptive Array Processing in GPS
Due to the extremely low power, GPS signal can be easily affected by interferences. In this paper, from the point of adaptive array processing, we review the existing spatial and space-time interference suppression methods which attempt to mitigate interferences before the GPS receiver performs correlation. These methods comprise self-coherence restoral technique based on the nature of GPS sign...
متن کاملMitigation of GPS Multipath Using Polarization and Spatial Diversities
This paper presents a GPS multipath mitigation method using a dual circularly polarized antenna array and a multi-channel receiver. The method is based on the exploitation of both polarization and spatial diversity associated with a GPS signal and its multipath signals available at the receiver input. Conventional GPS antennas are right-hand circularly polarized (RHCP) to suppress multipath con...
