However, GPS signals are easily affected by various errors, one of which is the multipath error. Multipath error refers to the signal reflection and refraction caused by scattering objects such as buildings and trees, which leads to a delay between the direct and reflected signals, resulting in errors in the measurement of the GPS position.To mitigate the multipath error, various anti-multipath algorithms have been proposed in the past few decades. Among them, code ring anti-multipath algorithm has been proved to be effective and efficient. The code ring anti-multipath algorithm involves the use of a special coding technique to spread the GPS signal and help the receiver differentiate between the direct and reflected signals.Purpose:The purpose of this research is to study the code ring anti-multipath algorithm for GPS receivers and propose an optimized algorithm to improve the accuracy of GPS positioning.Methodology:The research will involve a literature review of the current state-of-the-art anti-multipath algorithms for GPS receivers. The code ring anti-multipath algorithm will be compared with other existing algorithms, and its advantages and limitations will be analyzed. The simulation platform will be established to simulate the performance of the code ring anti-multipath algorithm under different conditions. Finally, an optimized algorithm will be proposed based on the analysis and results.Expected outcomes:The expected outcomes of this research include a comprehensive analysis of the code ring anti-multipath algorithm, its advantages, and limitations.
