An Adaptive Technique for the Mitigation of GPS Cross-Correlation
GPS is a CDMA system using DSSS, and the length of the C/A cod used by GPS L1 band civil signal is 1023chips. As the Cross-Correlation peak between the C/A codes is not zero, it will degrade the performance of the detection probability. Detection of weak signal is becoming important in many applications like GPS remote sensing etc. Cross-Correlation caused by GPS Gold codes are representing sig...
متن کاملAn Adaptive Multipath Mitigation Architecture for GPS System
In this paper, a multipath mitigation tracking system is presented for static GPS applications. It is comprised of four function blocks, those being (1) adaptive path estimator (APE), (2) multipath interference reproducer (MPIR), (3) Rake-based delay locked loop (RB-DLL), and (4) Rake-based phase locked loop (RB-PLL). Only the short delay condition with delay less than 1.5 PN chip is considered...
متن کاملMultipath Mitigation of Continuous GPS Measurements Using an Adaptive Filter
Though state-of-the-art dual-frequency receivers are employed in the Continuous GPS arrays (CGPS), the CGPS coordinate time series are typically very noisy due to the effects of atmospheric biases, multipath, receiver noise, etc., with multipath generally being considered the major noise contributor. An adaptive Finite-duration Impulse Response filter, based on a least-mean-square algorithm, ha...
متن کاملCross Correlation Mitigation Techniques for Software GPS C/A Code Receivers
The cross correlation properties of the 1023 chip Gold (C/A) codes can cause difficulties in scenarios where both strong and weak GPS signals need to be processed. Such cases are increasingly likely given the new applications of GPS, with examples being the processing of GPS signals in E911 cellular phone applications and the use of bistatic GPS as a remote sensing tool. This coupled with the i...
متن کاملSpoofing Mitigation of GPS Receiver using Least Mean Squares-Based Adaptive Filter
The Global Positioning System (GPS) signals are very weak signal over wireless channels, so they are vulnerable to in-band interferences. Therefore, even a low-power interference can easily spoof GPS receivers. Among the variety of GPS signal interference, spoofing is considered as the most dangerous intentional interference. The spoofing effects can mitigate with an appropriate strategy in the...
